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.

In recent years, the environmental testing industry has made remarkable progress. Many manufacturers have significantly improved the quality and technology of their temperature & humidity cycling test chambers.

The operation of the sand and dust test chamber primarily involves using a fan to blow sand and dust of the required concentration at an appropriate flow rate over the surface of the test sample.

The ozone aging test chamber is an instrument used in the aging resistance testing process of some materials.

With the continuous updating of GB/T 4208-2017, IEC 60529:2013, MIL-STD-810H and other domestic and international protection-class standards, “rain testing” has evolved from a simple “water-proof check” into a systematic evaluation covering sealing reliability, material weatherability, structural integrity, electronic compatibility and more.
