Forensics Hydrogen Cyanide Detector — HCN Gas Monitor (0-50 ppm, NIST)

Forensics Hydrogen Cyanide Detector — HCN Gas Monitor

The Forensics hydrogen cyanide detector measures HCN from 0-50 ppm with NIST calibration — a portable gas detector for fumigation, plating and fire overhaul, covering an acutely toxic gas the four-gas set doesn’t.

Jump to: Features · Specs · What it detects · Comparison · FAQ

The Forensics Hydrogen Cyanide Detector is a handheld, NIST-calibrated HCN gas monitor (0-50 ppm) with sound, light and vibration alarms for fumigation, electroplating and fire-overhaul use.

Key features

• Measures hydrogen cyanide (HCN) from 0-50 ppm — an acutely toxic gas outside the 4-gas set
• USA NIST-traceable calibration with certificate
• Sound, light and vibration alarms
• USB-rechargeable, compact 4.8 oz handheld
• For fumigation, electroplating, fire overhaul and combustion of plastics
• Covers a hazard a standard four-gas monitor cannot detect

Specifications

Where the Forensics HCN Detector fits

• Fumigation operations
• Electroplating shops
• Fire overhaul (HCN from burning plastics)
• Chemical manufacturing
• Confined-space HCN risk

What the Forensics HCN Detector detects (and what it doesn’t)

It detects hydrogen cyanide (HCN) only — not O2, combustibles, CO or H2S. For the four atmospheric gases use a Forensics 4 Gas Meter; for other single toxics see the Chlorine or Ammonia analyzers. HCN is lighter than air and acutely toxic, so set low alarms. Bump-test with HCN calibration gas and recalibrate on schedule.

Frequently asked questions

What does the Forensics HCN detector measure?

Hydrogen cyanide (HCN) from 0-50 ppm. It does not measure O2, LEL, CO or H2S — use a 4 gas meter for those.

Where is HCN detection needed?

Fumigation operations, electroplating, fire overhaul (HCN is released by burning plastics and foams), and some chemical manufacturing.

What is the OSHA limit for hydrogen cyanide?

OSHA sets a PEL around 10 ppm (skin) and ACGIH lists a low short-term limit; HCN is acutely toxic, so low alarm set points matter. Confirm current values for your program.

Is it NIST calibrated?

Yes — USA NIST-traceable calibration with certificate. Bump-test with HCN calibration gas and recalibrate on schedule.

Does it have a pump?

This model is diffusion. For a pumped specialty analyzer, see the Forensics Chlorine Analyzer or Hydrogen Analyzer.

How is it powered?

USB-rechargeable; it is a compact 4.8 oz handheld.

What alarms does it have?

Sound, light and vibration alarms trigger when HCN exceeds the set point.

Can it detect other gases?

No — HCN only. For chlorine use the Chlorine Analyzer; for ammonia the Ammonia Detector.

Why is HCN so dangerous?

Hydrogen cyanide is acutely toxic at low concentrations and interferes with the body's ability to use oxygen, which is why dedicated detection and low alarms are essential.

Is it in stock and how does it ship?

Use the Amazon buy button for current availability and delivery timing through our fulfillment partner.

Does the sensor need replacing?

Yes — electrochemical HCN sensors are consumables; replace per the manufacturer's schedule and verify against a known source.

Can I use it for confined-space entry?

HCN is one hazard; entry also needs O2, combustible and toxic testing with a portable 4-gas instrument.
