Hongjin Programmable Environment Climate Chamber Temperature and Humidity Test Chamber Climate Temperature and Humidity Test Equipment is used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. Suitable for quality testing of electronic, electrical, mobile phones, communication, instruments, vehicles, plastic products, metals, food, chemical, building materials, medical, aerospace and other products.
Dongguan Hongjin Testing Instrument Co., Ltd.was founded in June 2007 It is a high-tech manufacturing company that specializes in the design and automatic control of large-scale non-standard testing equipment like simulated environmental testing, material mechanics testing, optical dimension measurement, vibration impact stress testing, new energy physics testing, product sealing testing, and so on! We serve our customers with the utmost passion, adhering to the company concept of "quality first, honesty first, committed to innovation, and sincere service," as well as the quality principle of "striving for excellence."
The parts that need tobe checked in advance before testing the constant temperature and humidity box：
1. Check whether the alarm protection function is normal, whether the compressor is started, whether the pressure gauge of the compressor is checked, and whether there is any internal refrigerant leakage. If there is too little refrigerant, it is necessary to check and supplement the refrigerant to ensure that the test chamber is lowered normally.
2. Check if the condensing fan is running normally, check if the dust at the air inlet is too thick, check if the circulating fan inside the box is working properly, and check if the AC contactor and overload protector of the compressor are damaged; Check if the solenoid valve in the pipeline is open and if the solid relay in the heating system is damaged, affecting the cooling system.
3. The test chamber adopts an overlapping refrigeration method, where one compressor cannot work properly and the equipment cannot be lowered properly. Check whether the compressor control system is working properly and whether there is any abnormal noise or sound during the operation of the compressor, which can lead to the inability to lower.
4. Check if the data transmitted from the temperature sensor in the test chamber to the instrument is correct. If it is not normal, the compressor will also be unable to start.
