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.

Given that temperature and humidity alternating test chambers are expensive, it is crucial to keep certain precautions in mind when using the equipment to ensure better protection and maximize its value.

During the past twelve months, several third-party testing bodies and OEM laboratories reported the same problem: when running dust tests in accordance with GB/T 4208, IEC 60529 or MIL-STD-810, the batch cycle has stretched from 48 h to 72 h, even 96 h, while energy consumption has risen by more than 30 %.

Door locks, headlights, electrical dust covers, instrument panels, and other components can be tested for dust resistance using a sand and dust test chamber.

Recently, Linpin Instruments signed another contract with Shanghai Siemens for the environmental testing project at the high-voltage R&D center.
