PH3-B1 Phosphine Sensor

PH3 Gas Sensor, Electrochemical, B-Series, 0–10 ppm range
Low-range phosphine sensor for fixed safety and environmental monitoring

The PH3-B1 is a low-range 0–10 ppm phosphine sensor in the B-Series format, aimed at fixed gas detection and environmental monitoring in grain storage, fumigation and industrial safety applications. It provides 600–1,000 nA / ppm sensitivity at 5 ppm PH3, T90 < 20 s and very low noise, enabling precise low-ppm measurement. Operating life exceeds 24 months (24-month warranty), with well-defined temperature, zero and linearity characteristics to 10 ppm.
