Salt Spray (Fog) Test Chamber – Specifications & Features
Salt Spray (Fog) Test Chambers are designed to evaluate the corrosion resistance of materials and surface coatings under accelerated conditions. They produce a controlled salt fog environment to simulate long-term exposure to harsh coastal or industrial atmospheres.
