The constant temperature and Humidity Chamber is a kind of test for heat resistance, cold resistance and dry resistance of various materials (such as electronics, electrical appliances, communications, instruments, vehicles, plastic products, metals, food, chemicals, building materials, medical treatment, aerospace, etc.) , moisture-proof and other performance equipment.
The high-low Temperature Test Chamber is a device for testing the reliability of industrial products under high-low temperature or other performance indicators under the condition of high-low temperature (alternating) cyclic changes.

(1) The test in the constant temperature and humidity Test Chamber is generally carried out at a temperature of 15 degrees to 85 degrees, and the humidity can be 20% to 98% RH. Of course, it can also be done with lower humidity on request. We call it a low temperature and low humidity Test Chamber.
(2) The temperature of the high-low Temperature Test Chamber is generally -20 degrees or lower, and the humidity can be set (limited to 15~85 degrees).
Alternating heat and humidity test mainly means: within a certain period of time, the test is carried out under the condition that the temperature is kept constant and the humidity is at the rate of change you set before, and vice versa. There are also tests that require simultaneous changes in temperature and humidity at a set rate. The general constant temperature and humidity test is to control the humidity after reaching the temperature (alternation means that the temperature and humidity are controlled at the same time).
