A cold and hot shock test chamber is an environmental test equipment used to evaluate the performance and reliability of products under extreme temperature changes.

The composite salt spray test chamber breaks through the limitations of traditional constant-value tests. By cycling through salt spray, drying, and humidity-heat conditions, it accurately simulates the outdoor corrosion environment.

If the temperature recovery time falls outside the specified range, it can affect the test results of the thermal shock chamber. To routinely test the temperature recovery time of the equipment, you can follow the steps below.

UV weathering test chambers are typically equipped with either UVA-340 or UVB-313 cold-cathode fluorescent UV lamps. The spectral differences between the two types directly influence the acceleration factor and the reliability of test results.

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.
