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.
