This test chamber provides simulated environments of high temperature, low temperature, high humidity, and low humidity to test the degree of material 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. Test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. Suitable for quality control testing in industries such as electronics, electrical appliances, batteries, universities, research institutes, inspection and quarantine bureaus, paper products, food, vehicles, automotive parts, metals, chemicals, building materials, and other factories and units.
