Liquid thermal shock chamber (also known as a liquid-bath thermal shock chamber) is a type of equipment used for accelerated reliability stress testing. It features two separate temperature-controlled liquid bathsone for high temperatures and one for low temperatures. A basket mechanism rapidly and alternately immerses the test specimen into these high- and low-temperature heat-transfer liquid media. Leveraging the superior heat-transfer capacity of liquids compared to air, the system achieves e...

The answer is no. Please read below mentioned three reasons. Material and Manufacturing Mismatch: Constant temperature and humidity chamber wet-bulb gauze is mostly made of ordinary degreased cotton/blended fabrics, with short fibers and low density. Composite salt spray (salt spray + humidity + drying cycle) will cause the gauze to harden rapidly, form salt deposits, and shed fibers, clogging the nozzle and contaminating the sample. 2.
