• How to Prevent Condensation when Conducting Low-temperature Tests in a Temperature Test Chamber

  Oct 30, 2025

  When conducting low-temperature tests in a temperature test chamber, preventing condensation is a crucial and common issue. Condensation not only affects the accuracy of test results, but may also cause irreversible damage to products, such as short circuits, metal corrosion, and degradation of material performance.   The essence of condensation is that when the surface temperature of the product drops below the "dew point temperature" of the ambient air, water vapor in the air condenses into liquid water on the product surface. Based on this principle, the core idea for preventing condensation is to avoid the surface temperature of the product being lower than the dew point temperature of the ambient air. The specific methods are as follows:   Controlling the rate of temperature change is the most commonly used and effective method. By slowing down the rate of cooling or heating, the temperature of the product can keep up with the changes in ambient temperature, thereby reducing the temperature difference between the two and preventing the surface temperature of the product from falling below the dew point. 2. Use dry air or nitrogen to directly reduce the absolute humidity of the air inside the test chamber, thereby significantly lowering the dew point temperature. Even if the surface of the product is very cold, as long as the dew point of the ambient air is lower, condensation will not occur. It is usually used for products that are extremely sensitive to moisture, such as precision circuit boards and aerospace components, etc. 3. Local heating or insulation can ensure that the surface temperature of key components (such as circuit boards and sensors) is always above the dew point, which is more suitable for products with complex structures where only certain areas are sensitive to humidity. 4. Skillfully arrange the temperature cycle through programming to avoid exposing the product at the stage when condensation is most likely to occur. After the test is completed, do not directly open the box door in a normal temperature and humidity environment. Dry gas should first be introduced into the box and the temperature should be slowly raised to room temperature. After the product temperature has also risen, the box can be opened and taken out.   For a typical low-temperature test, the following process can be followed to prevent condensation to the greatest extent First, place the product and the test chamber in a standard laboratory environment for a sufficient period of time to stabilize their condition. Subsequently, within the range close to room temperature to "0°", set up one or more short-term insulation platforms. Or maintain it at the target low temperature for a sufficient period of time, during which the temperature inside and outside the product is consistent, and usually no new condensation will form. Also, set a heating rate that is slower than the cooling rate. Set up an insulation platform at the initial stage of temperature rise and when approaching the ambient temperature. After the temperature rise is completed, do not open the door immediately. Keep the box door closed and let the product stand in the box for "30 minutes to 2 hours" (depending on the heat capacity of the product), or introduce dry air into the box to accelerate the equalization process. After confirming that the product temperature is close to the ambient temperature, open the box door and take out the product.   The best practice is to use the above methods in combination. For instance, in most cases, "controlling the temperature variation rate" combined with "optimizing the test program (especially during the recovery stage)" can solve 90% of the condensation problems. For military or automotive electronics tests with strict requirements, it may be necessary to simultaneously stipulate the temperature variation rate and require the introduction of dry air.

• Dragon Heat Flow Meter Temperature Control Test

  Oct 29, 2025

  Temperature control tests are usually conducted under two conditions: no-load (without sample placement) and load (with standard samples or actual samples being tested placed). The basic testing steps are as follows:   1. Preparatory work: Ensure that the heat flow meter has been fully preheated and is in a stable state. Prepare high-precision temperature sensors that have undergone metrological calibration (such as multiple platinum resistance PT100), and their accuracy should be much higher than the claimed indicators of the heat flow meter to be measured. 2. Temperature uniformity test: Multiple calibrated temperature sensors are arranged at different positions within the working area of the heat flow meter's heating plate (such as the center, four corners, edges, etc.). Set one or more typical test temperature points (such as -20°C, 25°C, 80°C). After the system reaches thermal stability, simultaneously record the temperature values of all sensors. Calculate the maximum, minimum and standard deviation of these readings to evaluate the uniformity. 3. Temperature control stability and accuracy test: Fix a calibrated temperature sensor at the center of the heating plate (or closely attach it to the built-in sensor of the instrument). Set the target temperature and start the temperature control. Record the entire process from the start to reaching the target temperature (for analyzing response speed and overshoot). After reaching the target temperature, continuously record for at least 1-2 hours (or as per standard requirements), with a sampling frequency high enough (such as once per second), and analyze the recorded data. 4. Load test: Place standard reference materials with known thermal physical properties or typical samples to be tested between the hot plates. Repeat step 3 and observe the changes in temperature control performance under load conditions. Load will directly affect the thermal inertia of the system, thereby influencing the response speed and stability.   When you are choosing or using a heat flow meter, be sure to carefully review the specific parameters regarding temperature control performance in its technical specification sheet and understand under what conditions (no-load/load) these parameters were measured. Lab will provide clear and verifiable temperature control test data and reports.

• How is over-temperature protection carried out in a temperature test chamber?

  Oct 23, 2025

  The over-temperature protection of the temperature test chamber is a multi-level and multi-redundant safety system. Its core purpose is to prevent the temperature inside the chamber from rising out of control due to equipment failure, thereby protecting the safety of the test samples, the test chamber itself and the laboratory environment.   The protection system usually consists of the following key parts working together: 1. Sensor: The main sensor is used for the normal temperature control of the test chamber and provides feedback signals to the main controller. An independent over-temperature protection sensor is the key to a safety system. It is a temperature-sensing element independent of the main control temperature system (usually a platinum resistance or thermocouple), which is placed by strategically at the position within the box that best represents the risk of overheating (such as near the heater outlet or on the top of the working chamber). Its sole task is to monitor over-temperature. 2. Processing unit: The main controller receives signals from the main sensor and executes the set temperature program. The independent over-temperature protector, as an independent hardware device, is specifically designed to receive and process the signals from the over-temperature protection sensor. It does not rely on the main controller. Even if the main controller crashes or experiences a serious malfunction, it can still operate normally. 3. Actuator: The main controller controls the on and off of the heater and the cooler. The safety relay/solid-state relay receives the signal sent by the over-temperature protector and directly cuts off the power supply circuit of the heater. This is the final execution action.   The over-temperature protection of the temperature test chamber is a multi-level, hard-wire connected safety system designed based on the concepts of "redundancy" and "independence". It does not rely on the main control system. Through independent sensors and controllers, when a dangerous temperature is detected, it directly and forcibly cuts off the heating energy and notifies the user through sound and light alarms, thus forming a complete and reliable safety closed loop.

• Lab Aging Test Chamber Working Principle

  Oct 17, 2025

  Many products (such as rubber, plastic, insulating materials, electronic components, etc.) will age due to the combined effects of heat and oxygen when exposed to the natural environment over a long period of use, such as becoming hard, brittle, cracking, and experiencing a decline in performance. This process is very slow in its natural state. The air-exchange aging test chamber greatly accelerates the aging process by creating a continuously high-temperature environment and constantly replenishing fresh air in the laboratory, thereby evaluating the long-term heat aging resistance of materials in a short period of time.   The working principle of Lab aging test chamber mainly relies on the collaborative efforts of three systems: 1. The heating system provides and maintains a high-temperature environment inside the test chamber. High-performance electric heaters are usually adopted and installed at the bottom, back or in the air duct of the test chamber. After the controller sets the target temperature (for example, 150°C), the heater starts to work. The air is blown through the heater by a high-power fan. The heated air is forced to circulate inside the box, causing the temperature inside the box to rise evenly and remain at the set value. 2. The ventilation system is the key that distinguishes it from ordinary ovens. At high temperatures, the sample will undergo an oxidation reaction with oxygen in the air, consuming oxygen and generating volatile products. If the air is not exchanged, the oxygen concentration inside the box will decrease, the reaction will slow down, and it may even be surrounded by the products of the sample's own decomposition. This is inconsistent with the actual usage of the product in a naturally ventilated environment. 3. The control system precisely controls the parameters of the entire testing process. The PID (Proportional-integral-Derivative) intelligent control mode is adopted. The real-time temperature is fed back through the temperature sensor inside the box (such as platinum resistance PT100). The controller precisely adjusts the output power of the heater to ensure that the temperature fluctuation is extremely small and remains stable at the set value. Set the air exchange volume within a unit of time (for example, 50 air changes per hour). This is one of the core parameters of the air-exchange aging test chamber, which usually follows relevant test standards (such as GB/T, ASTM, IEC, etc.).   The test chamber creates a high-temperature environment through electric heaters, achieves uniform temperature inside the box by using centrifugal fans, and continuously expels exhaust gases and draws in fresh air through a unique ventilation system. Thus, under controllable experimental conditions, it simulates and accelerates the aging process of materials in a naturally ventilated thermal and oxygen environment. The biggest difference between it and a common oven lies in its "ventilation" function, which enables its test results to more truly reflect the heat aging resistance of the material during long-term use.

• How to Choose the Appropriate Cooling Method for Test Chambers？

  Sep 09, 2025

  Air cooling and water cooling are two mainstream heat dissipation methods in refrigeration equipment. The most fundamental difference between them lies in the different media they use to discharge the heat generated by the system into the external environment: air cooling relies on air, while water cooling relies on water. This core difference has given rise to numerous distinctions among them in terms of installation, usage, cost and applicable scenarios.   1. Air-cooled system The working principle of an air-cooling system is to force air flow through a fan, blowing it over its core heat dissipation component - the finned condenser, thereby carrying away the heat in the condenser and dissipating it into the surrounding air. Its installation is very simple and flexible. The equipment can operate simply by connecting to the power supply and does not require additional supporting facilities, thus having the lowest requirements for site renovation. This cooling performance is significantly affected by the ambient temperature. In hot summers or high-temperature environments with poor ventilation, due to the reduced temperature difference between the air and the condenser, the heat dissipation efficiency will drop markedly, resulting in a decline in the equipment's cooling capacity and an increase in operational energy consumption. Moreover, it will be accompanied by considerable fan noise during operation. Its initial investment is usually low, and daily maintenance is relatively simple. The main task is to regularly clean the dust on the condenser fins to ensure smooth ventilation. The main operating cost is electricity consumption. Air-cooled systems are highly suitable for small and medium-sized equipment, areas with abundant electricity but scarce water resources or inconvenient water access, laboratories with controllable environmental temperatures, as well as projects with limited budgets or those that prefer a simple and quick installation process.   2. Water-cooled system The working principle of a water-cooling system is to use circulating water flowing through a dedicated water-cooled condenser to absorb and carry away the heat of the system. The heated water flow is usually transported to the outdoor cooling tower for cooling and then recycled again. Its installation is complex and requires a complete set of external water systems, including cooling towers, water pumps, water pipe networks and water treatment devices. This not only fixes the installation location of the equipment, but also places high demands on site planning and infrastructure. The heat dissipation performance of the system is very stable and is basically not affected by changes in the external environmental temperature. Meanwhile, the operating noise near the equipment body is relatively low. Its initial investment is high. Besides electricity consumption, there are also other costs such as continuous water resource consumption during daily operation. The maintenance work is also more professional and complex, and it is necessary to prevent scale formation, corrosion and microbial growth. Water-cooled systems are mainly suitable for large, high-power industrial-grade equipment, workshops with high ambient temperatures or poor ventilation conditions, as well as situations where extremely high temperature stability and refrigeration efficiency are required.   Choosing between air cooling and water cooling is not about judging their absolute superiority or inferiority, but about finding the solution that best suits one's specific conditions. Decisions should be based on the following considerations: Firstly, large high-power equipment usually prefers water cooling to achieve stable performance. At the same time, the geographical climate of the laboratory (whether it is hot), water supply conditions, installation space and ventilation conditions need to be evaluated. Secondly, if a relatively low initial investment is valued, air cooling is a suitable choice. If the focus is on long-term operational energy efficiency and stability, and one does not mind the relatively high initial construction cost, then water cooling has more advantages. Finally, it is necessary to consider whether one has the professional ability to conduct regular maintenance on complex water systems.

• Lab Companion Vacuum Oven Working Principle

  Sep 02, 2025

  Lab Companion vacuum oven is a precision device that dries materials under low-pressure conditions. Its working principle is based on a core scientific principle: in a vacuum state, the boiling point of a liquid will significantly decrease. Its working process can be divided into three key links:   1. Vacuum creation: By continuously extracting air from the oven chamber through a vacuum pump set, the internal environment is reduced to a level far below atmospheric pressure (typically up to 10Pa or even higher vacuum degrees). This move achieves two purposes: First, it greatly reduces the oxygen content in the cavity, preventing the material from oxidizing during the heating process; The second is to create conditions for the core physical process: low-temperature boiling. 2. Heating provides energy: At the same time as the vacuum environment is established, the heating system (usually using electric heating wires or heating plates) starts to work, providing thermal energy for the materials inside the chamber. Due to the extremely low internal pressure, the boiling points of the moisture or other solvents contained in the material drop sharply. For instance, at a vacuum degree of -0.085MPa, the boiling point of water can be reduced to approximately 45℃. This means that the material does not need to be heated to the conventional 100℃, and the internal moisture can vaporize rapidly at a lower temperature. 3. Steam removal: The water vapor or other solvent vapors produced by vaporization will be released from the surface and interior of the material. Due to the pressure difference within the cavity, these vapors will rapidly diffuse and be continuously drawn away by the vacuum pump, then discharged into the external environment. This process is ongoing continuously, ensuring the maintenance of a dry environment and preventing steam from re-condensing within the cavity, thereby driving the drying reaction to proceed continuously and efficiently towards dehydration.   The "low-temperature and high-efficiency drying" feature of vacuum ovens makes them widely used in the fields of pharmaceuticals, chemicals, electronics, food, and materials science, especially suitable for processing precious, sensitive or difficult-to-dry materials by conventional methods.

• Application of high and low temperature test chambers in the research of new Energy materials

  Aug 30, 2025

  1. Lithium-ion batteries: High and low temperature tests run through all R&D stages of lithium-ion batteries, from materials, cells to modules. 2. Material level: Evaluate the basic physical and chemical properties of basic materials such as positive and negative electrode materials, electrolytes, and separators at different temperatures. For instance, testing the lithium plating risk of anode materials at low temperatures, or examining the thermal shrinkage rate (MSDS) of separators at high temperatures. 3. Cell level: Simulate the cold winter in the frigid zone (such as -40℃ to -20℃), test the low-temperature start-up, discharge capacity and rate performance of the battery, and provide data support for improving low-temperature performance. Cyclic charge and discharge tests are conducted at high temperatures (such as 45℃ and 60℃) to accelerate aging and predict the long-term service life and capacity retention rate of the battery. 4. Fuel cells: Proton exchange membrane fuel cells (PEMFC) have extremely strict requirements for the management of water and heat. Cold start capability is a key technical bottleneck for the commercialization of fuel cells. The test chamber simulates an environment below freezing point (such as -30℃) to test whether the system can be successfully started after freezing and to study the mechanical damage of ice crystals to the catalytic layer and proton exchange membrane. 5. Photovoltaic materials: Solar panels need to serve outdoors for more than 25 years, enduring the harsh tests of day and night as well as the four seasons. By simulating the temperature difference between day and night (such as 200 cycles from -40℃ to 85℃), the thermal fatigue of the interconnect solder tape of the battery cells, the aging and yellowing of the encapsulation materials (EVA/POE), and the bonding reliability between different laminated materials can be tested to prevent delamination and failure.   Modern high and low temperature test chambers are no longer simple temperature change chambers, but intelligent testing platforms integrating multiple functions. The advanced test chamber is equipped with observation Windows and test holes, allowing researchers to monitor the samples in real time during temperature changes.

• What should I do if the high and low temperature test chamber has problems?

  Jun 23, 2025

  High and low temperature test chamber may encounter a variety of problems in the process of use, the following is a summary of potential faults and their causes from different perspectives: 1. Core system failure Temperature out of control Reason: PID control parameters are out of balance, ambient temperature exceeds the design range of the equipment, multi-zone temperature interference. Case: In a special environment workshop, the external high temperature causes the refrigeration system to overload, resulting in temperature drift. Humidity is abnormal Reason: poor water quality of humidification leads to scaling and nozzle blockage, failure of ultrasonic humidifier piezoelectric sheet, and incomplete regeneration of dehumidification desiccant. Special phenomenon: reverse condensation occurs during high humidity test, resulting in the actual humidity in the box being lower than the set value. 2. Mechanical and structural problems Air flow is disorganized Performance: There is a temperature gradient of more than 3℃ in the sample area. Root cause: the customized sample rack changed the original design air duct and the accumulation of dirt on the centrifugal fan blade led to the destruction of dynamic balance.  sealing failure New failure: the magnetic force of electromagnetic sealing door decreases at low temperature, and the silicone sealing strip becomes brittle and cracks after-70℃. 3. Electrical and control system Intelligent control failure Software level: After firmware upgrade, the temperature dead zone setting error occurs and the historical data overflow causes the program to crash. Hardware level: SSR solid state relay breakdown causes continuous heating and bus communication is subjected to inverter electromagnetic interference. Security protection vulnerabilities Hidden dangers: the synchronous failure of the triple temperature protection relay and the false alarm caused by the expiration of the refrigerant detector calibration. 4. Challenges of special working conditions Specific temperature shock Problem: -40℃ to +150℃ rapid conversion of the evaporator weld stress cracking, thermal expansion coefficient difference resulting in the failure of the observation window seal. Long-term operation attenuation Performance degradation: after 2000 hours of continuous operation, the compressor valve plate wear leads to a decrease of 15% in refrigeration capacity and drift of ceramic heating tube resistance value. 5. Environmental and maintenance impact Infrastructure adaptation Case: The power oscillation of PTC heater caused by the fluctuation of power supply voltage and the water hammer effect of cooling water system damaged the plate heat exchanger. Preventive maintenance blind spots Lesson: Ignoring the positive pressure of the box leads to water entering the bearing chamber and biofilm growth and blockage in the condensate discharge pipe. 6. Pain points of emerging technologies New refrigerant application Challenges: system oil compatibility problems after R448A replaces R404A, and high pressure sealing problems of subcritical CO₂ refrigeration systems. IoT integration risks Fault: The remote control protocol is maliciously attacked, resulting in program tampering and cloud storage failure, resulting in the loss of test evidence chain. Strategy recommendations Intelligent diagnosis: configure vibration analyzer to predict the failure of compressor bearing, and use infrared thermal imager to scan the electrical connection points regularly. Reliability design: key components such as evaporator are made of SUS316L stainless steel to improve corrosion resistance, and redundant temperature control modules are added to the control system. Maintenance innovation: implement a dynamic maintenance plan based on operating hours, and establish an annual refrigerant purity testing system。 The solutions to these problems need to be analyzed in combination with the specific model of the equipment, the use environment and the maintenance history. It is recommended to establish a collaborative maintenance mechanism including the OEM of the equipment, third-party testing institutions and user technical teams. For key test items, it is recommended to configure a dual-machine hot standby system to ensure the continuity of testing.

• What should be paid attention to in summer when using the ice water impact test chamber?

  Jun 16, 2025

    When the Guangdong Hongzhan ice water impact test chamber is used in summer, the following matters should be paid special attention to to ensure the stable operation of the equipment and the accuracy of the test results: 1. Environment and heat dissipation management   Enhance ventilation and heat dissipation High temperature in summer is easy to lead to the decrease of equipment heat dissipation efficiency. Ensure that at least 10cm space is reserved around the equipment to promote air circulation. If the equipment adopts air cooling system, the condenser surface dust should be cleaned regularly to prevent poor heat dissipation and overheating of the compressor.Control the environmental temperature and humidity. Avoid placing the equipment in the direct sunlight area. It is recommended that the laboratory temperature be kept at 25±5℃ and the humidity be lower than 85%. High temperature and high humidity environment may accelerate the accumulation of frost or condensation water on the equipment, so it is necessary to increase the dehumidification measures. 2. Refrigeration system maintenance   Water quality and tank management Bacteria are easy to breed in summer, so use deionized water or pure water to avoid hard water scaling and blocking pipes. It is recommended to change the tank water every 3 days, and empty and clean the tank before long-term disuse.Refrigeration efficiency monitoring High temperature environment may lead to overload operation of the refrigeration system. The compressor oil condition should be checked regularly to ensure sufficient refrigerant. If the water temperature exceeds the set value (such as 0~4℃), the machine should be stopped immediately for troubleshooting. 3. Frosting and defrosting treatment   Prevent frost aggravation When the humidity is high in summer, the frost rate inside the equipment may accelerate. It is recommended to perform a manual defrosting process after 10 cycles: set the temperature to 30℃ and keep it for 30 minutes, and then drain water to clean the ice crystals on the evaporator surface. Optimize the test interval to avoid continuous long-term low temperature testing. It is recommended to reserve 15 minutes of buffer time between high temperature (e.g., 160℃) and ice water shock cycle to reduce the impact of thermal stress on the equipment. 4. Adjustment of operation specifications   Parameter setting optimization According to the characteristics of the summer environment, the normal temperature recovery stage time can be shortened appropriately (the reference standard is to complete the temperature switch within 20 seconds), but it must ensure that it meets the requirements of GB/T 2423.1 or ISO16750-4 standards.Safety protection should be strengthened. Anti-freezing gloves and goggles should be worn during operation to avoid the adhesion of hands and low-temperature parts caused by sweating. Before opening the door after high temperature test, the temperature inside the box should be confirmed to be below 50℃ to prevent scalding from hot steam. 5. Emergency and long-term shutdown preparation   Fault response If the equipment has E01 (temperature out of tolerance) or E02 (water level abnormal) alarm, you should immediately cut off the power supply and contact the technical support of the manufacturer. Do not disassemble the refrigeration pipeline by yourself.Long-term protection When not used for more than 7 days, the water tank should be emptied, power should be cut off and dust cover should be covered. At the same time, power should be on for 1 hour every half a month to keep the circuit board dry.   Through the above measures, the impact of high temperature and humidity environment in summer on the ice water shock test chamber can be effectively reduced to ensure the reliability of test data and the service life of the equipment. The specific operation details should be adjusted according to the equipment manual and actual working conditions.
