SMART SENSOR ST8904 4-in-1 Poisonous Hazardous and Combustible Gas Detection Alarms

SMART SENSOR ST8904 4-in-1 Poisonous Hazardous and Combustible Gas Detection Alarms

Features:

• This professional 4-in-1 gas detector is designed for detecting CO, H₂S, O₂, and LEL gas

• It can continuously monitor the CO, H₂S, O₂, and LEL gas concentration in the surrounding environment. Once the gas concentration reaches the alarm level, the alarm will sound, vibrate, and flash

• This high-precision portable CO, H₂S, O₂, and LEL gas tester is compact and lightweight, making it very easy to carry and operate

• 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/vibration/flash triple alarms work when one of the CO, H₂S, O₂, & LEL gas concentration reaches the level of the alarm

• Large HD LCD display with backlight for easy reading

• Can connect to a sampling pump to operate in the closed place

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