2. Purpose

The rapid temperature change test chamber is used to test the performance of materials in various environments and test the heat, cold, dry and moisture resistance of various materials. It is suitable for testing the quality of electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products.

It is used to test and determine the parameters and performance of electrical, electronic and other products and materials after undergoing high temperature, low temperature, alternating humidity or constant test after temperature environment changes. Finished product lighting test to verify the reliability of the product under high temperature and high humidity conditions.
