SS2148 (NO₂)

Electrochemical NO₂ Sensor (0–20ppm)

DESCRIPTION

The SS2148 is an electrochemical sensor designed for accurate detection of nitrogen dioxide (NO₂) in the range of 0–20 ppm. It features a linear output of 220 ± 50 nA/ppm, a fast T90 response time under 30 seconds, and high sensitivity with a resolution below 0.1 ppm. With excellent long-term stability and low cross-sensitivity to interfering gases such as CO, H₂, H₂S, NO, and SO₂, this sensor is ideal for use in vehicle maintenance shops, parking ventilation control, air quality monitoring, and industrial safety systems.
