SS2198 Hydrogen Sulfide Sensor – High-Performance H₂S Detection for Industrial Safety
SS2198 is a high-sensitivity electrochemical sensor designed to detect hydrogen sulfide concentrations in the range of 0 to 100 ppm.
It delivers a strong linear output signal (700 ± 200 nA/ppm), a fast T90 response time under 20 seconds, and a resolution of less than 0.1 ppm, making it suitable for low-level H₂S detection.
The sensor exhibits minimal cross-sensitivity to other gases such as CO, H₂, SO₂, NO, and NO₂, ensuring accurate performance in complex gas environments.
With over 24 months of operating life and excellent repeatability, SS2198 is an ideal solution for use in petrochemical facilities, sewage systems, refineries, mines, and confined space monitoring.
