NH3-AF Ammonia Sensor

NH3 Gas Sensor, Electrochemical, A-Series, 0–100 ppm filtered

Compact, filtered ammonia sensor for portable and fixed safety instruments

The NH3-AF is a 0–100 ppm ammonia sensor in the A-Series package, designed for industrial safety, agriculture and environmental monitoring. With 15–40 nA/ppm sensitivity and T90 ≈ 300 s to 50 ppm, it supports stable NH3 measurement while its filter limits cross-sensitivity to H2S and other gases. An operating life > 24 months (24-month warranted) and defined temperature behaviour make NH3-AF a solid choice for OEMs needing reliable NH3 detection in portable and fixed equipment.
