1. Brief Introduction:

Mixed gas test chamber is used for accelerated corrosion testing of contact points and connectors, to evaluate the corrosion effects of the atmosphere contaminated by sulfur combustion products on contact points and connectors.

The test chamber utilizes gases such as H2S, SO2, NO2, CI2, etc., to accelerate corrosion of materials or products under specific temperature and relative humidity conditions, reproducing the corrosion effects of materials or products over a certain period of time.

The extent of damage within the scope and a comparison of the process quality of similar protective layers, assessing the protective coatings of industrial products such as automotive parts, electronic components, metal materials, and electrical products in a mixed gas environment.

Corrosion resistance in the body.
