A Salt Spray Chamber, also known as a Salt Fog Chamber, is an equipment used to test the corrosion resistance of materials and surface coatings. This testing apparatus simulates a highly corrosive environment, usually by spraying a saltwater solution (typically a 5% sodium chloride solution) into a test chamber atmosphere at a controlled temperature. The main purpose of this Salt Spray Chamber is to replicate the effects of saltwater or sea spray in a controlled setting, providing rapid results on how materials will withstand such conditions over time.
