READY STOCK SIAP KIRIM

Features Smart Sensor Multi Gas Monitor ST8900 4 in 1 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.
