Detailed explanation of the characteristics of some technologies used in the high and low temperature test chamber

(1) Selection of the size of the high and low temperature test chamber No matter whether you buy the equipment yourself or see the Dongguan high and low temperature test box bought by someone else, you usually ask, what is the size of this test box? It can be seen that users value the size of the test chamber. In fact, when choosing the high and low temperature test chamber, we must understand that it cannot be filled like a refrigerator. The best ratio of the test piece to the space of the test box is 1:3, which helps to reduce the air in the high and low temperature test chamber. Circulation. To

(2) Selection of control method The high and low temperature test chamber is divided into two situations: alternating and without alternating. To

The common control method of the high and low temperature test chamber is: set a target temperature, and the test box has the ability to automatically keep constant temperature to the target temperature. The high and low temperature alternating test box has a program to set one or more high and low temperature changes and cycles, and the test box has the ability to complete the test process according to the preset curve. Therefore, in the choice of the high and low temperature test chamber with alternating and without alternating, the user should consider the actual test situation before making a choice. If you simply do a high-temperature and low-temperature test, I still recommend choosing an ordinary high-low temperature test box to save more money.

Conversely, if the the high and low temperature test chamber you use is more frequent and the test methods are changeable, then the high and low temperature alternating test box will be able to play a better advantage.
