Precision Salt Fog & Humidity Test Chambers — Built to the Standards That Drive Industry
Engineered for accuracy and repeatability, the Auto Technology SFC Salt Fog & Humidity Test Chamber delivers dependable performance for ASTM B117, ISO 9227, and MIL-STD 810 corrosion standards. Designed for continuous operation and precise environmental control, the SFC reproduces salt spray and humidity exposure conditions to evaluate coatings, components, and materials with exceptional consistency. Built in the USA and trusted by laboratories worldwide, it provides the proven reliability and uniformity demanded by standards-driven testing programs.
Whether you’re validating coatings, fasteners, or components, the Auto Technology Salt Fog & Humidity Chamber provides repeatable, traceable, and certifiable test conditions — the same chambers we use in our own A2LA-accredited corrosion test lab.
