SMART SENSOR 4 in 1 Gas Monitor Rechargeable Portable Gas Detector H₂S O₂ CO and LEL Multi Gas Monitor Professional Gas

Feature: 1. Detect 4 kinds of gas: carbon monoxide(CO), hydrogen sulfide(H₂S), oxygen(O₂) and combustible gas(LEL). 2. Continuously monitor the CO, H₂S, O₂ and LEL gas concentration in the surrounding environment with professional and accurate measurement. 3. Sound vibration flash triple alarms works when one of the CO, H₂S, O₂ \u0026 LEL gas concentration reaches the level of the alarm. 4. Large HD LCD display with backlight for easy reading. 5. Can connect to a sampling pump to operate in closed place. 6. Can be widely used in shipping, mining, oil exploitation, chemical, gas pipeline, tunnel construction, coal, metallurgy, paper, fire, municipal, textile and other industries. Specification: 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, vibration and flash. High precision portable CO, H₂S, O₂ and LEL gas tester with compact size and light weight, very easy to carry and operate.
