Constant humidity and heat test chamber/Constant temperature and humidity test chamber

Product Introduction：

The constant temperature and humidity test chamber can generally be divided into programmable constant temperature and humidity test chambers (touch screen)/Button type and single point constant temperature and humidity test chamber. Used to test the degree to which material structures or composite materials can withstand continuous environments of extremely high and low temperatures, in order to test the chemical changes or physical damage caused by thermal expansion and contraction. Applicable objects include metal, plastic, rubber, and electronics……Waiting for materials can serve as a basis or reference for product improvement

Product detailed introduction：

◇Product Features
1.Arc shaped and surface spray treated, with a high-quality appearance and a flat non reactive handle, easy to operate, safe and reliable.
