Corrosion Gauges

The corrosion tester is a laboratory instrument used to check the corrosion resistance of materials and coatings. The test involves exposing a sample to a controlled saline mist in a sealed chamber for a specified period, typically ranging from a few hours to several days. Test conditions, such as salt concentration, temperature, and exposure duration, can be adjusted based on specific testing requirements.

Corrosion testers (salt spray testers) are widely used in industries such as automotive, aerospace, shipping, and electronics to evaluate the corrosion resistance of materials and coatings under harsh environmental conditions, especially in salt and humidity environments. The test results can help in selecting the appropriate materials and coatings for a specific application or in assessing the effectiveness of anti-corrosion protection measures.

The test is based on the principle that salty water is an extremely corrosive agent and exposure to a salt-filled environment can cause corrosion of materials, resulting in loss of strength, appearance, and functionality. By subjecting materials to controlled salt spray conditions, a corrosion tester can simulate the effects of long-term exposure to salty water and provide a rapid assessment of the materials' corrosion resistance.
