FAQ
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. What is the usable inner volume of the TAHW-12m³-5, and how should test samples be arranged inside the chamber?
The TAHW-12m³-5 provides an inner chamber volume of 12 cubic meters (W2000×D3000×H2000 mm), making it well-suited for large-scale battery modules and oversized test samples. Samples should be placed on the standard test rack with sufficient spacing between items to allow uniform airflow throughout the chamber. Avoid blocking air inlet and outlet openings, and do not exceed the maximum structural load capacity specified in the user manual, as overloading may compromise temperature and humidity uniformity.
5. Does the chamber support fully programmable test cycles and remote data monitoring?
Yes. The built-in 7-inch TFT touch screen controller supports fully programmable temperature and humidity profiles, including customizable ramp rates, step hold times, and cycle repeat counts. Test data is automatically logged in real time and can be exported for analysis and reporting. Remote monitoring is available via mobile APP and PC, enabling users to view live parameters and receive alarm notifications. The interface also supports multiple language selections for international use.
6. What routine maintenance is recommended to keep the chamber operating reliably over the long term?
Recommended routine maintenance includes: regularly replenishing distilled or deionized water in the humidification system; inspecting and cleaning the water-cooled condenser and cooling water circuits; checking door seals for wear and replacing as needed; verifying the calibration accuracy of temperature and humidity sensors at scheduled intervals; and confirming the operational status of the explosion-proof lighting, smoke alarm, and fire suppression systems. Full maintenance schedules and procedures are provided in the user manual, and our 24-hour technical support team is available for remote guidance or on-site service arrangements.
