SS2138 (NO)

Electrochemical Nitric Oxide Sensor (0–500ppm)

DESCRIPTION

The SS2138 is an electrochemical sensor designed for accurate detection of nitric oxide (NO) concentrations from 0 to 500 ppm. It features a fast T90 response time under 15 seconds, high sensitivity with resolution below 0.5 ppm, and a linear output of 350 ± 50 nA/ppm with excellent repeatability within ±2%. With near-zero cross-sensitivity to common gases such as CO, H₂, NH₃, and SO₂, it is ideal for automotive service stations, diesel emission monitoring, industrial ventilation systems, and air quality monitors.
