Product Description:
YJJ 4HCN CLE-0731-400 Electrochemical Hydrogen Cyanide Sensor for Safety Monitoring Leakage Alarm Detection
Features:
1. Core Parameters (Taking - 4HCN / CLE-0731-400 as an example) Table
Parameter item Typical value Explanation
Detected gas Cyanogen Hydride (HCN) Highly toxic, colorless, bitter almond smell gas
Detection principle Tri-electrode electrochemistry Concentration is proportional to output current
Measurement range 0 - 50 ppm Industrial safety standard range (the immediate lethal concentration is approximately 50 ppm)
Overload capacity 100 ppm Does not damage for a short period
Sensitivity 0.10 ± 0.02 μA/ppm About 0.1 microampere current is generated per ppm of HCN
Response time (T90) ≤ 120 seconds Response speed to 90% concentration
Resolution 0.1 - 0.2 ppm Minimum concentration change detectable
Operating temperature -20℃ - +50℃ Industrial wide temperature range
Operating humidity 15 - 90% RH (no condensation) Conventional industrial environment
Service life 2 - 3 years in air Normal service life
Size φ20 × 16.6 mm Standard 4 Series (4Series) industrial size
Power supply / bias voltage 0 mV (no bias voltage required) Directly compatible with transmitters
II. Main applications (Why use 4HCN)
HCN is highly toxic: Inhaling 50 ppm for several minutes can cause death → 4HCN is a safety sensor for life
1. Industrial safety (most important)
Electroplating industry (gold plating, copper plating, silver plating): Cyanide electrolyte is prone to volatilization HCN
Mining / metallurgy: Gold mines, silver mines cyanide leaching process for gold extraction
Chemical / fiber: Synthetic resins, acrylonitrile, pesticide production
Steel / coking: Blast furnace, coke oven by-product HCN
Fire / emergency: Plastic, silk, wool combustion in fires produces highly toxic HCN
2. Environment and municipal
Wastewater treatment plants, garbage incineration, safety detection in enclosed spaces (sewer, ship cabins)
Atmospheric environmental monitoring stations: Trace HCN monitoring
3. Equipment applications
Portable HCN detector (handheld alarm)
Fixed gas detector (wall-mounted / pipeline installation)
Online analysis system, safety PLC interlock
Marine safety equipment (detection of residual HCN from rat extermination in ship cabins)
