I received a consultation from the customer today, what is the difference between the hot and cold shock test chamber and the high and low temperature test chamber? Which device is better? If we go to any device in Baidu, Baidu will show that they are the same device, but they still have a difference.
Although both the thermal shock test chamber and the high and low temperature test chamber are an environmental testing device for testing materials for high and low temperature exchange experiments, both temperature control is very accurate.
To say that they are different in the word "impact" of the thermal shock box, the device is subjected to sudden changes in temperature and temperature during high temperature and low temperature exchange, and the high and low temperature changes of the high and low temperature test chamber are It changes gently, or it changes temperature at a steady temperature change rate, which is the difference between the two devices. The reason for this difference is that the experimental results are different because of the different working principles of the two.
In addition, the inside of the thermal shock test chamber generally has two compartments, which are divided into a high temperature zone and a low temperature zone. When the article is tested, the article is mainly moved back and forth to form a hot and cold impact environment; while the high and low temperature test box has only one cabinet. The high temperature and low temperature tests are carried out in this tank, so when the temperature needs to change, it is often faced with a process of cooling or warming, and the efficiency is lower than that of the cold and hot shock test chamber.
The above is the difference between the two devices. Because the working principle of the two is different, the test results are different, so it is not said that the device is better. Everyone should choose according to their own needs.
