Walk In Constant Humidity Heat Test Chamber For Testing Solar Panel IEC60068-2
Product Information For Walk-In Corrosion Humidity-Heat Test Chamber:
Solar panel walk-in constant temperature and humidity test chamber is mainly designed and manufactured according to standards of IEC 60068-2-78, IEC 1251:1993, IEC 61730 and etc. It is used to test photovoltaic modules and determine the ability of modules to withstand long-term moisture penetration. The purpose is to determine the ability of modules to resist heat cycles and humidity-heat tests. It is also suitable for ESS high and low temperature cyclic stress screening test or constant test for electrical and electronic products and other products, parts and materials, and for quality and reliability testing of products, parts and materials under simulated temperature changes.
The test room adopts PLC intelligent central integrated control, touch screen display and operation, it is equipped with sample placement brackets, and a slope at the entrance of the test room. The samples are convenient to be moved and placed. The whole system is simple to operate, and the whole machine is beautiful and generous.

System Principle For Walk-In Salt Spray Corrosion Humidity-Heat Test Chamber:
The PLC is used to control the cooling of the compressor, the heating of the heat pipe and the humidification of the humidifier, cooperating with the indoor air duct to realize the control of the temperature and humidity in the chamber.
Forced circulation ventilation, balance temperature regulation method. The control system controls the output of the heater through the PID automatic calculation output according to the temperature point set by the system, and finally reaches a dynamic balance.
Chamber structure For Walk-In Corrosion Humidity-Heat Test Chamber:
The test chamber consists of a control cabinet, a chamber body, a sample mounting bracket and a slope.
