SS2158 Sulfur Dioxide Sensor – High-Performance SO₂ Detection with Built-in H₂S Filter
SS2158 is a high-accuracy electrochemical gas sensor designed to detect sulfur dioxide (SO₂) in the range of 0 to 20 ppm.
It features a linear output of 250 ± 100 nA/ppm, a fast response time under 30 seconds (T90),
and a typical resolution of less than 0.1 ppm.
The sensor includes a built-in H₂S interference filter rated for 1000 ppm·hours, ensuring reliable operation in complex gas environments.
With long-term output drift below 15% per annum and a lifespan of over 24 months in air,
SS2158 is ideal for use in industrial safety monitors, ambient air quality devices, and automotive emission control systems.
