The salt fog humidity cyclic corrosion test chamber is more complex and closer to the real environment than the traditional single salt spray test chamber, including salt spray, humidity, drying and temperature cycles, which are commonly used to assess the corrosion resistance of various materials and coatings. The salt spray humidity cyclic corrosion test chamber is to ensure the reliability and service life of materials and products in coastal, marine, high humidity and corrosive environment.

Product details

Salt Fog Humidity Cyclic Corrosion Test Chamber

Sample Holder

Customized insert sample holders and fixtures allow for flexibility and ease in meeting test accuracy and stability based on sample shape, quantity, size, and test requirements.

Salt Water Mixing System

The bubble-type brine stirring system continuously injects air into the brine tank to form uniform bubbles that stir the liquid, effectively preventing salt sedimentation.

Pneumatic Open/Close Lid

Pneumatic open/close lids provide a safe, more precise test environment. It ensures consistent opening and closing every time, especially in environments where high precision testing is required, ensuring equipment and sample stability.

Refrigeration System

The refrigeration system lowers the air temperature, causing the water vapor in the moist air to condense and be discharged on the surface of the evaporator. This process provides ideal conditions for the drying cycle or humidity conversion stage.
