Frequently Asked Questions
1. What is the main difference between the thermal shock test chamber and the high/low temperature cycling test chamber (wet heat chamber)?
The core difference between the two lies in the temperature conversion speed: The cold and heat shock box can complete the switching between high and low temperatures within 10 seconds and return to stability within 5 minutes, used to test the product's tolerance to extreme temperature differences in an instant. The cycle test box, on the other hand, slowly changes temperature at a set rate of 1 to 3 degrees Celsius per minute, mainly simulating the gradual change process of the natural environment climate.
2. What are the requirements for the water used in the hygrothermal test chamber?
It is recommended to use distilled water or deionized water (with resistivity ≥ 500Ω·m). The impurities present in tap water can easily cause scaling in the humidification cylinder and blockage of the wet bulb cloth, thereby affecting the accuracy of the humidity sensor.
3. What should be done if the equipment gives an alarm?
This equipment's control system supports bilingual (Chinese and English) fault self-diagnosis. When there are faults such as overheating, water shortage, or compressor overpressure, the screen will automatically display detailed alarm information and handling solutions. You can follow the prompts to troubleshoot by yourself. If the problem remains unsolved, you can call our 24-hour after-sales hotline. We will provide remote video guidance or arrange on-site service within 48 hours.
4. How does the remote monitoring and control system operate?
The test chamber comes equipped with independently developed controller software and a 7-inch TFT true-color touchscreen. It supports seamless remote connectivity via mobile APP and PC workstations, featuring multi-language interface switching, real-time temperature curve tracking, and remote parameter configuration.
5. What safety systems are integrated to ensure secure testing operations?
The chamber is engineered with comprehensive multi-layer safety devices, including explosion-proof pressure relief systems, smoke exhaust mechanisms, internal fire extinguishing and sprinkler units, smoke alarms, leakage protection, compressor overpressure interlocks, and real-time video surveillance.
6. What are the installation requirements regarding power supply and cooling?
The chamber requires a 3-phase AC 380V (140KW) industrial power connection and an external circulating water-cooling subsystem for optimal operation. Our service team provides full on-site installation, commissioning, and operator training to ensure correct setup.
