The SS3198 is a miniature 3-electrode electrochemical sensor designed for precise hydrogen sulfide (H₂S) measurement in the 0–100 ppm range. It offers a strong output of 700 ± 200 nA/ppm, a fast response time of under 20 seconds, and a resolution of less than 0.1 ppm. The sensor is optimized for stable performance in compact devices and maintains high accuracy even in complex environments due to its low cross-sensitivity to interfering gases such as CO, H₂, SO₂, NO, and NO₂. Ideal for portable and fixed detection systems used in petrochemical plants, mining, and wastewater treatment facilities.
