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. Poor Corrosion Resistance: Salt spray contains high concent...
