4 In 1 Gas Detector CO H₂S O₂ LEL Monitor Digital Handheld Toxic Carbon Monoxide Hydrogen Sulfide Air Quality Tester Detector

This profeional 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 envment, 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 envment with profeional and accurate measurement. Intelligent voice, 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. It adopts advanced integrated circuit technology, embedded computer control, high-quality gas , with excellent sensitivity and repeatability. It uses dot matrix LCD display to support Chinese-English interface and Chinese-English voice prompt, so that users can quickly understand the product and use and maintain it simply. High-strength engineering plastics, good seismic resistance, high strength, high-tmospheric appearance and dust-proof, waterproof and explosion-proof function. Stainle steel buckle, the back with a shelf can be fixed on the outside of the tooling, firmly clamped and not easy to fall. USB charging interface, 3.7V/1800mAh lithium battery, convenient and fast, fully charged can be used continuously for more than 10 hours. Can be widely used in shipping, mining, oil exploitation, , gas line, tunnel construction, coal, metallurgy, paper, fire, municipal, textile and other industries.
