"" This professional 4-in-1 gas detector can continuously monitor the concentration of CO, H2S, O2 and LEL in the environment. Once the gas concentration reaches the alarm level, the alarm sounds, turns on and vibrates. High precision portable and portable gas tester CO, H2S, O2 and LEL, compact and light in size, very easy to carry and use.
Made from a quality material, very sensitive and precise measurement.
Detection of 4 gases: oxygen / carbon monoxide / hydrogen sulfide / combustible gas.
Gas measurement range:
Oxygen: 0 ~ 30% vol; Carbon monoxide: 0 ~ 999ppm; Hydrogen sulfide: 0 ~ 500ppm; Fuel: 0 ~ 100% LEL
High and low alarm function with three alarm methods: When the gas concentration reaches the preset high or low alarm value, the meter will emit an audible and light alarm with vibration, the high and low alarm value may be adjusted according to your specific needs.
Digital LCD screen with backlight function: real-time gas concentration value, high density, LCD screen display, backlight function suitable for dark areas
Durable power supply: built-in 3.7 V rechargeable Li-thion battery, capable of operating continuously for 18 hours on a full charge (slightly variable depending on working conditions).
Compact size and unique clip design: It is convenient for the user to carry and use it.
