SS4198 (H₂S)

Electrochemical H₂S Sensor (0~200ppm)

DESCRIPTION

The SS4198 is a high-precision electrochemical hydrogen sulfide (H₂S) sensor that measures gas concentrations in the 0–200 ppm range. It offers a stable output of 380 ± 80 nA/ppm, a fast T90 response time of under 35 seconds, and a resolution of less than 0.1 ppm. With a lifespan of over 24 months and low cross-sensitivity to interfering gases, the sensor ensures accurate detection in complex environments. It is ideal for portable and fixed detectors used in oil refining, petrochemical, wastewater treatment, mining, and confined spaces.
