Constant temperature and humidity test chamber (high and low temperature alternating humidity test chamber)

application

Compliant with temperature and humidity testing standards, the air circulation system can simulate testing conditions in different environments such as high temperature, low temperature, low temperature, and high temperature. Paired with an easy to operate and learn high-precision programming system, it provides the best testing performance conditions and is widely used for adaptability testing of electrical, electronic, instrumentation, and other product components during storage, transportation, and use in high temperature, low temperature, and humid environments. It determines the temperature resistance adaptability of the above products to high temperature, low temperature, and humid environments, especially the changes in electrical and mechanical properties of the products，It can also be used to check the ability of the sample to withstand certain corrosion
