High and low temperature test chamberScope of Application：

High and low temperature test chamber:，Provide environments with 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. It can also simulate the container environment to detect the fading and shrinkage of rubber and plastic in high temperature and high humidity environments.Specially test the heat resistance, cold resistance, dry resistance, and moisture resistance of various materials. Suitable for quality testing in electronic, electrical, instrument, food, vehicle, metal, chemical, building materials, aerospace, medical, product and other fields.
