ST8900 SMART SENSOR 4-in-1 Multi Gas Detector in Pakistan
The ST8900 SMART SENSOR Multi Gas Detector is a portable 4-in-1 gas monitoring instrument designed to simultaneously detect and monitor Carbon Monoxide (CO), Hydrogen Sulfide (H₂S), Oxygen (O₂), and Combustible Gas (LEL). With a large LCD display, configurable high and low alarms, and sound, light, and vibration alerts, the ST8900 is designed for continuous gas monitoring in industrial and workplace environments.
This SMART SENSOR ST8900 gas detector provides real-time concentration readings for four gases on a single display, allowing users to monitor potentially hazardous atmospheric conditions more efficiently. Its portable handheld design makes it suitable for applications involving oil and gas, mining, chemical industries, gas pipelines, tunnels, construction, metallurgy, fire safety, municipal services, shipping, and industrial maintenance.
The ST8900 supports gas measurement ranges of 0–999 ppm for CO, 0–500 ppm for H₂S, 0–30%VOL for O₂, and 0–100%LEL for combustible gas. The instrument uses a rechargeable 3.7V BL-9C battery and provides approximately 6 hours of operating time without an alarm condition.

What Is the ST8900 Multi Gas Detector?
The ST8900 SMART SENSOR is a multi-gas monitoring instrument designed to detect four important atmospheric hazards: carbon monoxide (CO), hydrogen sulfide (H₂S), oxygen (O₂), and combustible gas expressed as %LEL.
Unlike a single-gas detector, this 4-gas detector allows users to monitor multiple gas concentrations using one portable instrument. The measured values are shown on the LCD display, while audible, visual and vibration alarms can alert the operator when configured alarm conditions are exceeded.

ST8900 Gas Detector Alarm System
The ST8900 uses a three-mode alarm system consisting of sound, light and vibration alerts. This provides the operator with multiple warning methods when a gas concentration reaches a configured alarm condition.
Audible Alarm
The audible alarm provides an immediate sound alert when the configured alarm threshold is exceeded.
Visual Alarm
The visual alarm provides a light-based warning that can help the operator identify an alarm condition quickly.
Vibration Alarm
The vibration alert provides an additional warning method for situations where an audible alarm may be difficult to notice.
High, Low and STEL/TWA Alarm Functions
The ST8900 supports configurable high and low alarm settings and includes STEL/TWA alarm functionality for exposure-monitoring applications.
What Gases Does the ST8900 Detect?
Carbon Monoxide (CO)
CO is a hazardous gas that can be generated by incomplete combustion. The ST8900 measures carbon monoxide from 0 to 999 ppm with a resolution of 1 ppm.
Hydrogen Sulfide (H₂S)
