NO2-B43F Nitrogen Dioxide Sensor

NO2 Gas Sensor, Electrochemical, B-Series, 0–20 ppm NO2

Best-in-class baseline stability for fixed outdoor and roadside air quality monitors

The NO2‑B43F is a high‑stability PPB‑level NO2 sensor engineered for fixed air‑quality monitoring networks and high‑humidity environments. Its O2 filter design ensures accurate low‑level NO2 readings, and its B‑Series package offers long‑term robustness. IST versions further simplify deployment across multi‑node monitoring systems.
