GasDetector IR-220

The GasDetector IR 220 refrigerant sensor is used where refrigerants can leak. Many synthetic refrigerants are dangerous for humans and nature – they are mostly toxic, harmful to the climate or even explosive.

The GasDetector IR 220 reliably detects refrigerant leaks and can thus provide early warning. This is important because refrigerant leakage is a risk, but one that can be managed by using intelligent gas detection and warning systems.

Technical data

  • Detection of refrigerant gases in the ppm range
  • High gas selectivity
  • Measuring range: 0 … 2000 ppm
  • Measuring principle: non-dispersive infrared technology (NDIR)
  • Long sensor life
  • low dependence on temperature and humidity
  • High precision and repeatability
  • High resistance to chemical toxins
  • One-man calibration
  • lineares Messsignal 4 … 20 mA
  • integrated switching outputs for:
    Alarm 1 (pre-alarm)
    Alarm 2 (main alarm)
    Sensor fault
