Classification of high and low temperature test chambers

According to test methods and industry standards, high and low temperature test chambers can be divided into alternating test and constant temperature test. Both test methods are upgraded and expanded on the basis of high and low temperature test chamber. Alternate test chamber means that the required high temperature, low temperature and temperature time can be set at one time within the instrument parameters, and the test chamber will be carried out according to the set procedures. The high and low temperature test chamber is making a fixed temperature, which makes the test effect closer to the natural climate and simulates the worse natural climate, thus making the tested samples more reliable.
