Product Description

The constant temperature and humidity test chamber provides a simulated environment of high temperature, low temperature, high humidity and low humidity to detect the deterioration degree of the material and strength of rubber, plastic and electronic products before and after the test. This machine can also simulate the container environment to detect the discoloration and shrinkage of rubber and plastic under high temperature and high humidity. Test the heat, cold, dry and wet resistance of various materials. The high and low temperature humidity and heat alternating test chamber is suitable for electronics, electrical appliances, batteries, universities, research institutes, inspection and quarantine bureau, paper products, food, vehicles, auto parts, metals
