The SS4198_HT is an electrochemical hydrogen sulfide (H₂S) sensor optimized for accurate detection in high-temperature, low-humidity environments. It provides precise measurement within a 0–100 ppm range, with an output of 650 ± 150 nA/ppm and a response time of under 20 seconds (T90). With an operating temperature range up to +70℃, the sensor shows no response to CO or H₂ and minimal cross-sensitivity to SO₂. It is well-suited for fixed gas detection systems in petrochemical plants, refineries, sewage treatment, and mining operations.
