SMART SENSOR ST8904 Gas Monitor 4 in 1

SMART SENSOR ST8904 Gas Monitor 4 in 1

Professional Multifunctional Gas Detector Oxygen O2 Hydrogen Sulfide H2S Carbon Monoxide CO Combustible Gas LEL Gas Meter

 

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.
