HCN-A1 Hydrogen Cyanide Sensor

HCN Gas Sensor, Electrochemical, A-Series, 0–100 ppm range
A-Series hydrogen cyanide sensor for portable and fixed safety analyzers

The HCN-A1 is a 0–100 ppm hydrogen cyanide sensor in the widely used A-Series package, designed for portable and fixed monitors used in industrial safety, firefighting, mining and environmental applications. With 45–85 nA / ppm sensitivity at 30 ppm HCN and T90 < 70 s, it delivers fast and stable response over a broad temperature range. The sensor has characterised cross-sensitivities and a 12-month warranty, with typical operating life > 12 months.
