Portable 4in1 gas detector, it is a kind of concentration of instrument that can continuous detect the concentration of O2, EX,CO,H2S gas in the working environment. The detector detects gas concentration with natural diffusion mode, which uses the imported sensors and has a good sensitivity and repeatability.
