Cooling is a critical aspect of constant temperature and humidity test chambers. The two most common cooling methods are water-cooled (chilled water) and air-cooled. Each has its own advantages and disadvantages.

The salt spray test chamber is primarily used to evaluate the corrosion resistance of test samples. It is widely applied in industries such as electrical engineering, digital accessories, plastic products, and aerospace manufacturing to assess the corrosion resistance of products and simulate their performance under extreme environmental conditions.

Rain test chambers simulate water exposure environments to evaluate the waterproof performance of objects. Everyday items such as exterior lighting fixtures, automotive lamp housings, electronic products, and signaling equipment can be tested using this device to assess their waterproof capabilities.

High-low temperature cycling test chambers are common and frequently used testing devices in our daily lives.

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.
