The temperature shock test chamber is one of the most difficult test equipment in the environmental testing industry, and its price is cheaper than 100,000. It is used to test the degree of the endurance of the material structure or composite material in a continuous environment of extremely high temperature and extremely low temperature in an instant, which can detect the chemical change or physical damage caused by the thermal expansion and contraction of the sample in the shortest time.

Everyone knows that the temperature shock test box is divided into two box type and three box type. The three box type is divided into a high temperature area, a low temperature area and a test area. The difference between the two box type and the three box type is that the test method and internal structure are different. In terms of structure: the two-box type is divided into a high temperature area and a low temperature area. The three box type is divided into a high temperature area, a low temperature area and a test area. The two-box temperature shock test box places the sample in the basket, and it moves up and down with the basket during operation. The motor drives the basket to move between high and low temperature. The three-box temperature shock test box prevents the test sample from being tested in the test area.

Both the two-box and three-box temperature shock test chamber can meet the temperature change test N of GB / T2423.1-2001, GB / T2423.2-2001, GB / T2423.22-1989, and the national military standard GJB150.3-86 , National Military Standard GJB150.4-86, National Military Standard GJB150.5-86GJB150.5-86, GJB360.7-87, GJB367.2-87 405 and other standards.
