Smart Sensor ST8900 4 in 1

Detektor 4 macam gas dalam 1 alat dari Smart Sensor.
Mendeteksi:
1. Oksigen (O2)
2. Karbon Monoksida (CO)
3. Hidrogen Sulfida (H2S)
4. Gas mudah meledak (LEL)

Features:
- 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
- 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.
