Programmable high and low temperature test chamber

1programmableHigh and low temperature test chamberPurpose:

This equipment is mainly designed for adaptability testing of electrical and electronic products, their raw components, and other materials during storage, transportation, and use in environments with normal temperature and cyclic changes. This experimental equipment is mainly used for testing products according to***Requirement or user-defined requirement: Conduct environmental simulation tests on the physical and other related characteristics of the product under normal temperature and cyclic change conditions. After testing, determine the performance of the product through testing to see if it still meets the predetermined requirements for product design, improvement, identification, and factory inspection
