HCN-H4 Hydrogen Cyanide Sensor

HCN Gas Sensor, Electrochemical, H-Series Miniature, 0–50 ppm range
Miniature H-Series hydrogen cyanide sensor for wearable personal safety.

The HCN-H4 is a miniature 0–50 ppm hydrogen cyanide sensor in the H-Series package, aimed at compact, wearable personal safety monitors in mining, firefighting and industrial environments. With 30–50 nA / ppm sensitivity at 20 ppm HCN, T90 < 50 s and low noise, it offers fast, stable response in a very small footprint. The sensor provides > 12-month operating life (12-month warranty) with characterised temperature and humidity performance
