Product Description
Model OC-901 portable gas detector is specially configured with imported electrochemical sensor for CO (Carbon Monoxide) monitoring. Adopts built-in pump suction sampling method to realize rapid gas suction and fast response measurement. The device supports independent CO single detection or mixed detection with other gases (O2, H2S, LEL, VOC etc.). Equipped with triple alarm of sound, light, vibration plus voice broadcast warning, effectively remind staff of CO concentration over-limit in toxic and high-risk working sites. It is an essential safety protection device for industrial CO leakage inspection, confined space operation, boiler room, metallurgy and chemical industry scenarios.
