Falco: VOC Gas Detector with PPM and PPB Capability

Ion Science's Falco fixed VOC Gas Detector, Diffused model, is a fixed VOC gas detector that eliminates false readings that impede other competing technology while providing constant detection of Volatile Organic Compounds (VOCs) in dangerous environments.

The Falco Diffused instrument is ideal for detecting VOCs throughout industry premises, like refineries and petrol chemical facilities.

Features

The Diffused, fixed Falco VOC gas detector consists of an Intrinsically Safe sensor that is situated externally for simple and rapid servicing that does not need a hot work permit. The dual certification implies that Falco can be serviced and calibrated in dangerous environments without needing to disconnect from power.

Both the Pumped and Diffused standard Falco models come fitted with a 10.6 eV lamp. This allows an extensive range of instrument detection in comparison to VOC gases. Four detection ranges are available on this fixed gas detector, including 0–10 ppm, 0–50 ppm, 0–1000 ppm and 0–3000 ppm.

To determine Total Aromatic Compounds (TACs) on both the pumped TAC and diffused TAC models, which focus on benzene, the Falco TAC uses a 10.0 eV lamp. The detection range of the Falco TAC 0–50 ppm.

Ultimate Performance

  • The only VOC detector developed for severe weather
  • Sophisticated sensor performance considerably decreases drift and downtime
  • Typhoon technology prevents the formation of condensation with the PID

Ultimate Safety
