Constant temperature and humidity test chamber http://www.ruihongshiye.com.cn/
High and low temperature test box manufacturers are necessary testing equipment in the fields of aviation, automotive, home appliances, scientific research and other fields. Performance, low temperature range from 0 ℃ to -160 ℃.
I. High and low temperature test chamber manufacturers Applicable industries and national standards:
The parameters and performance of electronic and other products and materials after high temperature, low temperature, or constant temperature environment changes, the low temperature range can be from 0 ° C to -160 ° C.
Test reference standards are: GB / T2423.1, GB / T2423.2-2008 low temperature test standards. GB 10589-89 standard
Control system of high and low temperature test box manufacturers:
The temperature control uses Japanese UMC, touch-control setting, digital and direct display, and the temperature control output power is calculated by PID microcomputer to achieve high precision and high efficiency power consumption benefits. If an error occurs, a Jingxun number will be provided.
Refrigerators are imported from France "Taikang", Germany "Bizer", the United States "Copeland" fully enclosed compressors, all imported from abroad.
Dry filters, refrigerant flow windows, repair valves, oil separators, solenoid valves, and liquid reservoirs are all imported original parts
The refrigeration system is designed with a unit or binary low temperature loop system.
The low temperature test box uses a multi-wing blower for strong air circulation to avoid any dead angles, which can make the temperature distribution in the test area uniform.
The air circuit is designed to circulate air and return air. The wind pressure and wind speed meet the test standards, and the temperature can be stabilized quickly when the door is opened.
Heating, cooling, and complete system independence can improve efficiency, reduce test costs, increase life, and reduce failure rates.
The overall equipment is over temperature; the overall equipment is out of phase / reverse phase; the overall equipment is overloaded; the refrigeration unit is overpressured; the overall equipment is timing;
There are other protections such as leakage, running instructions, automatic shutdown after a fault is reported.
