Brand: Smart Sensor
Specifications
SKU: Smart Sensor 4 in 1 ST8904 Gas Monitor Rechargeable Portable Gas Detector H₂S O₂ CO and LEL Multi Gas Monitor GasSniffer
Continuous Monitoring with Alarms:Continuously monitors gas levels and alerts with sound, vibration, and flash when thresholds are reached.
Portable and Lightweight Design:Compact and lightweight design makes it easy to carry and operate in diverse settings.
Extended Battery Runtime:Offers up to 6 hours of operation without alarms, ensuring long-lasting use.
Gas Carbon Monoxide Detector|St2084|Multifunctional Gas Detection:Detects CO, H₂S, O₂, and LEL gases, ensuring comprehensive safety monitoring in various environments.
High Precision Sensors:Equipped with electrochemical sensors for accurate and reliable gas detection.
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 level of the alarm, the alarm will sound, vibration and flash. High precision portable CO, H₂S, O₂ and LEL gas tester with compact size and light weight, very easy to carry and operate.
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 with professional and accurate measurement.
Sound/vibration/flash triple alarms works 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 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.
