Technical parameters of multi-layer constant temperature and humidity test chamberapplication

This test chamber provides environments of high temperature, low temperature, high humidity, and low humidity to compare the material changes and strength attenuation of rubber, plastic, electronic products, and other materials before and after testing. This machine can also simulate the container environment to detect the fading and shrinkage of rubber and plastic under high temperature and humidity. This machine is specifically designed to test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials.
