The difference between a high and low temperature impact test chamber and a high and low temperature

High and Low Temperature Impact Test Chamber and High and Low Temperature Humidity Changing Impact Test Chamber sound similar in name, even in appearance, but the High and Low Temperature Impact Test Chamber is the like There are significant differences between high and low temperature cycling humidity and heat test chambers. This is mainly manifested in the following three aspects:yhoTextile Testing Instruments, Testing Equipment Manufacturer

First, the structure of the high and low temperature impact test chamber is different from that of the high and low temperature alternating humidity heat test chamber, a high and low temperature impact test box with two boxes and a high and low temperature three box impact test box, while the high and low temperature alternating damp heat impact test box has only one working space. yhoTextile Testing Instruments, Testing Equipment Manufacturer

Second, the rate of change of the test temperature is different. The main function of the high and low temperature impact test chamberis to carry out the thermal shock test of the product, such as -40 degrees and 100 degrees for the product In the impact test, the temperature change time is within 15 seconds, that is, the product is first tested in an environment of -40 degrees for several hours, and then exposed to a high temperature of 100 degrees within 15 seconds (the stabilization time is 5 minutes). The high and low temperature alternating damp heat test chamber can not do such a test, and the high and low temperature damp heat test chamber can do separate low temperature, high temperature and damp heat tests It gives a time course for the gradual change, and the high and low temperature impact test chamber can not be used for humidity testing.
