High and low temperature impact test chamberSuitable for reliability testing of industrial products at high and low temperatures, it is the testing of various performance indicators of components and materials of electronic and electrical products, automobiles and motorcycles, aerospace, marine weapons, universities, research institutions and other related products under high and low temperature alternating cycles.

　　

　　High and low temperature impact test chamberThe temperature calibration methods include the following methods. In practical work, it is necessary to choose the most suitable method according to the actual situation. Below, our company will introduce the advantages and disadvantages of these calibration methods.

　　

1、 Calibration under no-load conditions: The advantages of this method are that the entire working area of the high and low temperature impact test chamber is calibrated, there is no need to recalibrate when the test sample becomes larger, and the applicability of the high and low temperature test chamber can be effectively evaluated. And its main drawback is that it cannot evaluate the impact of the test sample on the test chamber.

　　

2、 Calibration under loaded conditions: The advantage of this method is that it can accurately evaluate the impact of the test sample on the performance of the test chamber and easily obtain detailed information on the environmental testing of key components or parts of the test sample. And its main disadvantage is that when replacing the test sample, it needs to be recalibrated.

　　

3、 Real time measurement during use: This method not only has the advantages of the methods described in 1 and 2, but also can obtain comprehensive environmental parameters of the test sample during environmental testing, which is often used in product testing with high environmental requirements. Its main disadvantage is that measurement equipment is required for each environmental test, and the calibration method under no-load conditions is usually used for calibration of the test chamber. In order to facilitate the evaluation of the temperature performance of the test chamber, this method is also used for analysis in this article.
