SS2158 (SO₂)

Electrochemical Sulfur Dioxide Sensor (0–20ppm)

DESCRIPTION

The SS2158 is an electrochemical sensor designed to accurately detect sulfur dioxide (SO₂) within a 0–20 ppm range. It features an output of 250 ± 100 nA/ppm, a fast response time of less than 30 seconds (T90), and a high resolution below 0.1 ppm. A built-in H₂S interference filter (capacity: 1000 ppm·hours) ensures stable performance in various industrial environments. With a lifespan of over 24 months in air and an operating temperature range of -20℃ to +50℃, the SS2158 is ideal for applications such as industrial safety, air quality monitoring, and vehicle emission control.
