What are the constant temperature and humidity Test Chambers and high-low Temperature Test Chambers?
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.
The difference between high-low Temperature Test Chamber and constant temperature and humidity Test Chamber
From the test temperature of high-low Temperature Test Chamber and constant temperature and humidity Test Chamber:
(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).
If the cycle of high temperature, low temperature and humidity is to be realized at the same time, a humid heat Test Chamber with alternating high-low temperature, a constant temperature and humidity Test Chamber, etc. should be used;
The high-low Temperature Test Chamber is only used for the cycle of high temperature and low temperature, without humidity;
Generally, the constant temperature and humidity Test Chamber can do "alternating damp heat test", but it depends on the test conditions. If you wish to purchase equipment, you should advise the supplier of the requirements prior to purchasing the equipment. Make the equipment can be designed and debugged as required. Of course, the price is not the same according to the requirements you mentioned.
