SMART SENSOR 4 in 1 Gas Detector H₂S and CO Monitor Industrial Digital Handheld Toxic Gas Carbon Monoxide Detector

This professional 4 in 1 gas detector is designed for detecting CO, H₂S, O₂ and LEL gas. It can continuously monitor the CO, H₂S, O₂ and LEL gas concentration in the surrounding environment, once the gas concentration reaches the level of the alarm, the alarm will sound, light and vibrate. High precision portable CO, H₂S, O₂ and LEL gas tester with compact size and light weight, very easy to carry and operate.  

Features:
Detect 4 kinds of gas: carbon monoxide(CO), hydrogen sulfide(H₂S), oxygen(O₂) and combustible gas(LEL).
Continuously monitor the CO, H₂S, O₂ and LEL gas concentration in the surrounding environment with professional and accurate measurement.
Sound & light vibration alarm works when one of the CO, H₂S, O₂ & LEL gas concentration reaches the level of the alarm.
Can set automatic shutdown time and concentration of alarm value.
Large color LCD display with backlight for easy reading.
Can connect to a sampling pump to operate in closed place.
Can be widely used in shipping, mining, oil exploitation, chemical, gas pipeline, tunnel construction, coal, metallurgy, paper, fire, municipal, textile and other industries.
