Low pressure test chamberIt is mainly used in the fields of aviation, aerospace, electronics, etc., to determine the reliability of instruments, electrical products and materials subjected to high and low temperature repeated effects under low pressure conditions, demonstrating their adaptability to this environment. It consists of an insulation box, refrigeration system, and vacuum unit controller. For the aviation and aerospace industry, even a small error can lead to accidents. Therefore, the low pressure test box is an indispensable inspection instrumentLow pressure test chamberWhat are the requirements for its use?

*The experimental environment requires the temperature of the instrument installation environment to be between 5 ℃ and 30 ℃, with an average temperature of less than 30 ℃, and the surrounding humidity should be ≤ 85% RH.

Secondly, in terms of water supply, the water used in the experiment is pure water, distilled water, and deionized water, with a resistivity of ≥ 500 Ω· m. This ensures the accuracy of the experiment and prevents the use of tap water from reducing the lifespan of the test chamber.

Thirdly, during the experiment, try to avoid opening and closing the test box door multiple times, as this may cause fluctuations in temperature and humidity inside the test box, and may also cause the refrigeration system and heat exchanger to malfunction.

The above are some issues that I have summarized that should be paid attention to when using a low-pressure test chamber. Only by seriously considering these common problems can we obtain accurate numbers during the testing process

It can also reduce the problem of decreased instrument lifespan caused by these small errors.
