circuit board80L high and low temperature test chamberPurpose:

High and low temperature test chamberSuitable for testing the adaptability of electrical, electronic, instrumentation, and other products, components, and materials to complex high and low temperature humid and hot environments during storage, transportation, and use. This testing equipment is mainly used to conduct environmental simulation tests on the physical and other related characteristics of products under high temperature, low temperature, humid and hot conditions in accordance with national standards or user defined requirements. After testing, the performance of the product is judged through inspection to determine whether it still meets the predetermined requirements, in order to facilitate product design, improvement, identification and factory inspection.
