ZhongAn S316 pump suction gas detector is a multi-in-one gas detector. It can continuously detect combustible, oxygen, carbon monoxide, hydrogen sulfide and other toxic gases in ambient air, and detect up to 5 gases at the same time. This instrument is waterproof design and combine with rubber shell, to meet the harsh requirements of harsh environment.
ZhongAn S316 gas detector uses pump-suction mode for detecting, and high quality gas sensors are used for sensitive components, which has excellent sensitivity and repeatability. The instrument is controlled by embedded micro-computer. It has simple operation, complete functions, high reliability, multiple adaptive abilities, and is intuitive and clear with graphic and text liquid crystal display.
