SS21CH Dual Gas Sensor – Simultaneous Detection of CO and H₂S in One Compact Package
SS21CH is a dual-channel electrochemical gas sensor capable of detecting both carbon monoxide (0–500 ppm) and hydrogen sulfide (0–200 ppm) simultaneously.
With a response time of under 30 seconds and a resolution of ≤0.5 ppm, it ensures rapid and precise detection in safety-critical environments.
The sensor is optimized for use in portable multi-gas detectors, industrial safety monitors, residential CO alarms, and environmental gas monitoring in wastewater or mining.
It offers low cross-interference between the two channels, excellent repeatability, and stable performance over a 24-month operating life.
