Designed for precision and repeatability, it exposes metals, coatings, and components to sulfur dioxide (SO2), hydrogen sulfide (H2S), nitrogen dioxide (NO2), and chlorine (Cl2) gases under controlled temperature, humidity, and concentration conditions. This equipment provides accelerated corrosion testing to identify vulnerabilities in materials and ensure product durability under extreme toxic gas environments.Designed to comply with international standards such as ASTM G85, ISO 3231.
Engineered to precisely replicate industrial and natural gas-corrosive conditions, it supports long-duration tests and multi-step programmable cycles for predictive analysis of material and coating performance. Its advanced control system ensures uniform gas distribution, stable temperature and humidity, and safe operation even under toxic gas exposure.
