The SS2198_HT is an electrochemical hydrogen sulfide (H₂S) sensor designed for stable performance even in high-temperature and low-humidity environments. It accurately measures H₂S concentrations from 0 to 100 ppm, with an output signal of 450 ± 80 nA/ppm and a fast response time under 30 seconds (T90). The sensor does not react to CO or hydrogen, and offers excellent selectivity with minimal cross-sensitivity to SO₂, NO, and NO₂. With a maximum operating temperature of +70℃ and a service life exceeding 24 months, the SS2198_HT is ideal for fixed installations in petrochemical plants, wastewater treatment, mining, and pipe interiors.
