SMART SENSOR Multi-Gas Meter is a portable and handheld instrument that is capable to use continuously monitoring four different gas:CO, H₂S, O₂,LEL,when detected these gases,all the concentration will disolayes on the LCD.The unit also provided user to configure high and low alarms,also have STEL/TWA alarm function.The unit has audio and vibration visual alarm once the alarn condition is exceeded

Product Features

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 & light vibration alarm works when one of the CO, H₂S, O₂ & LEL gas concentration reaches the level of the alarm.

4.Can set automatic shutdown time and concentration of alarm value.

5.Large color LCD display with backlight for easy reading.

6.Can connect to a sampling pump to operate in closed place.

7.Can be widely used in shipping, mining, oil exploitation, chemical, gas pipeline, tunnel construction, coal, metallurgy, paper, fire, municipal, textile and other industries.
