The temperature shock test chamber, also known as a thermal shock test chamber or high-low temperature impact test chamber, is a device used to simulate extreme temperature variations under controlled environmental conditions.

Salt fog (salt spray) test chambers are standardized instruments designed to determine the corrosion resistance of materials and their protective coatings. The test results serve as a technical basis for reliability design, quality control, and service-life prediction in industries such as electrical and electronic engineering, digital components, plastics, aerospace equipment, and many others.

Salt spray test chambers evaluate the corrosion resistance of samples by exposing them to a corrosive salt mist, allowing comparison with other products. These tests can be categorized into three types

The refrigeration compressor is one of the key components affecting the test results of a high and low temperature test chamber. To ensure smooth operation, proper maintenance of the compressor is essential. During daily operation, the following actions must be avoided

Salt-spray cabinets artificially intensify corrosive agents so that months or even years of marine or industrial atmospheric attack are reproduced within a few hours or days. This paper systematically describes the working mechanism of the equipment, the control logic of its critical parameters, and the quantitative correspondence between test results and natural exposure. The aim is to provide industry with the technical basis for tailoring test programmes to specific products.
