Hydrogen Sulfide (H2S) Sensor Module

Compact Air Quality Sensor for PPB Level H2S Monitoring

Oizom offers several Hydrogen Sulphide (H2S) sensors for ambient air quality monitoring. The Hydrogen Sulphide (H2S) Sensor Module is designed to accurately measure low concentrations of H2S in ppb/ppm levels in ambient air, making it an ideal tool for real-time monitoring of H2S emissions from point sources.

Design

This sensor module is designed with advanced support electronics that enhance its compactness and reliability. Its low-noise electronics ensure stable and precise detection of H2S, even at concentrations below 10 ppb. The sensor works on the electrochemical principle, known for its high sensitivity to H2S and its stable response to transient changes in relative humidity. The advanced 4-electrode sensor technology includes two high-sensitivity electrodes specifically for H2S detection, while the other two electrodes counteract the effects of ambient conditions, ensuring accurate measurements. This makes the H2S Sensor Module an excellent choice for indicative real-time air quality monitoring in outdoor environments.
