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.

If the temperature and humidity test chamber is a powerful tool for evaluating product performance, then the operators are the ones who wield this tool—and a critical factor that directly influences test results.

In the composition of high - low temperature test chambers, the refrigeration compressor is undoubtedly a core component, and its selection directly determines the quality of the test results. In fact, semi - hermetic refrigeration compressors are predominantly used in high - low temperature test chambers.

Regularly, staff should master some troubleshooting and handling methods for high and low temperature alternating test chambers. If the equipment exhibits unstable low temperatures, what causes this phenomenon, and how should we address these faults?

This guide regulates the daily start-up/shut-down, parameter setting, sample loading, process monitoring and maintenance of laboratory constant-temperature and humidity test chambers (hereafter “the chamber”), ensuring personnel safety, equipment reliability and data traceability.
