For chemical plant managers & mining safety directors: The MST101 detects hazardous gases in 25s (T90) to prevent workplace leaks—ATEX/CE certified for explosive environments.
MST101 series portable gasdetectoris a advanced detectioninstrument,with fall alarm function,OLED display screen, visible under sunlight. The shell is designed with rubber coated,whichhas good water and dust resistance. The use of anti-static materialscan meet the explosion-proof requirements. It can continuouslydetect the concentration of toxic gas or oxygen in the ambient air of industrial and mining enterprises,with sensitive reaction and convenient carrying. It has been widely used in iron and steel metallurgy,chemical plant,petrochemical industry,emergency rescue, industrial safety and other industries.MST101 series portable gas detector is one type of advanced single gas analyzer. It's very small ,light weight to easy carry and OLED display screen makes the workers read date clearly under sunlight or other places. Otherwise, the shell of detector is designed by rubber coated plastic mould and anti-static materials, which has good waterproof performance, also can meet the explosion-proof requirements. MST101 fully charge can work 30 days . It has been widely used in iron and steel metallurgy, petrochemical industry, emergency rescue, industrial safety and other industries.
