In the aerospace, automotive, home-appliance and materials-science sectors, products must routinely undergo prolonged and repeatable exposure within the −80 °C to 0 °C range to verify functional integrity and service life under extreme cold. Nature cannot supply a continuous, controllable and stable sub-zero environment; consequently, low-temperature test chambers are employed to create an artificial cryogenic duty.

Previously, we have discussed many technical aspects of temperature cycling test chambers. Today, we will share methods for detecting leaks in these chambers. Specifically, there are four main approaches to check for leaks.

Correctly connecting the compressed air hose is fundamental for the normal operation of a temperature shock test chamber.

High-low temperature test chambers are the cornerstone of environmental reliability testing. The quality of their performance directly determines the credibility of product qualification and the length of the R&D cycle.

Some users of high and low temperature alternating test chambers complain that their equipment is not durable.
