Product Description
Smart Sensor ST8900 4 in 1 Gas Detector
This instrument is a portable multi-gas detector, which can continuously detect 4 kinds of gases at the same time: O2, LEL (combustible gas), CO, H2S. Each gas concentration reading will be displayed on the LCD screen. The instrument allows the user to set the low concentration/high concentration alarm setting value and the STEL/TWA alarm function. When the detection result exceeds the preset alarm setting value, the instrument will remind the user with sound, light and vibration alarm.
Features Smart Sensor ST8900 4 in 1 Gas Detector:
- Detect 4 kinds of gas: carbon monoxide(CO), hydrogen sulfide(H₂S), oxygen(O₂) and combustible gas(LEL).
- Continuously monitor the CO, H₂S, O₂ and LEL gas concentration in the surrounding environment with professional and accurate measurement.
- Sound & light vibration alarm works when one of the CO, H₂S, O₂ & LEL gas concentration reaches the level of the alarm.
- Can set automatic shutdown time and concentration of alarm value.
- Large LCD display with backlight.
- Can connect to a sampling pump to operate in closed place.
- Widely used in shipping, mining, oil exploitation, chemical, gas pipeline, tunnel construction, coal, metallurgy, paper, fire, municipal, textile and other industries.
