HCN-D4 Hydrogen Cyanide Sensor

HCN Gas Sensor, Electrochemical, D-Series, 0–50 ppm range
Miniature hydrogen cyanide sensor for clip-on and compact portable devices

The HCN-D4 is a miniature 0–50 ppm hydrogen cyanide sensor in the D-Series format, ideal for slim personal monitors and compact portable analyzers. Sensitivity is 30–50 nA / ppm at 20 ppm HCN, with T90 < 50 s and low zero noise to support reliable alarm triggering. Operating life exceeds 12 months (12-month warranted), with defined performance over typical industrial temperature and humidity ranges.
