Function and Use
The constant temperature and humidity test machine can simulate different test conditions such as high temperature and high humidity/high temperature and low humidity/low temperature and high humidity/low temperature and low humidity. It is widely used in aerospace, military, electronics, electrical appliances, petroleum, chemical, coatings, plastics, post and telecommunications, medical and pharmaceutical, colleges and universities, scientific research institutions and other industries to conduct environmental reliability tests on products for temperature and humidity resistance.
Test Principle
The constant temperature and humidity test machine adopts a balanced temperature and humidity control system (BTHC) to control the SSR in a P.I.D. way, so that the heating and humidification amount of the system is equal to the heat and humidity loss, allowing the machine to operate stably for a long time.
Comply with standards
GB/T2423.1-2008 low temperature test method, GB/T2423.2-2008 high temperature test method, GB/T2423.3-2006 test Cab: constant humidity and heat, GB/T2423.4-2008 test Db: alternating humidity and heat test method GB/T2423.34-2005 test Z/AD: humidity and heat combination or other temperature and humidity tests within the performance range of the equipment.
