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)
