Product Overview
This test chamber simulates the temperature and humidity changeable environment for the products or materials. It is widely used in the adaptability test of electrical, electronics, instrument and meter and other product parts under high and low temperature and humid environment during storage, transportation and usage, to determine the temperature adaptability of the above products or materials to high and low temperature and humid environment, especially for product electrification changes in performance and mechanical properties.
