Hydrogen Cyanide (HCN) Detectors

We supply fixed and portable hydrogen cyanide gas detectors to safeguard workers in high-risk environments. Fixed systems provide continuous monitoring for plant-wide safety, while portable detectors allow individual workers to assess exposure during maintenance, confined space entry, or emergency response.

Our hydrogen cyanide detection range includes solutions from leading manufacturers such as BW, Crowcon, Dräger, GMI, Honeywell, MSA, RAE Systems, Riken Keiki, and Uniphos. Portable models may also be available for hire.

Ensure worker safety and maintain operational compliance with our fixed and portable hydrogen cyanide detection systems, trusted in chemical, mining, and manufacturing industries.

HCN monitoring is typically performed using electrochemical sensors with high sensitivity to parts-per-million concentrations, ensuring fast and accurate detection. Regular calibration is essential to maintain reliability and compliance with occupational safety requirements.

Hydrogen cyanide (HCN) is a highly toxic and flammable gas with a faint bitter almond odour, widely used in chemical production, mining, electroplating, and plastics manufacturing. It interferes with the body’s ability to use oxygen, making it extremely dangerous even at very low concentrations. Acute exposure can lead to headache, dizziness, nausea, and respiratory failure, while high levels can be fatal within minutes.
