Fixed VOC Gas Detector: Falco Diffused

The Falco fixed VOC Gas Detector, Diffused model, is a fixed VOC gas detector that eradicates false readings that hinder other competing technology while offering continuous detection of Volatile Organic Compounds (VOCs) in hazardous areas.

The Falco Diffused instrument is perfect for detecting VOCs across industry premises, such as refineries and petrol chemical facilities.

Features

Falco Diffused, fixed VOC gas detector has an Intrinsically Safe sensor that is located externally for swift, easy servicing that does not require a hot work permit. Dual certification means that Falco can be calibrated and serviced in a hazardous environment without the need to remove power.

Both the Pumped and Diffused standard Falco models come equipped with a 10.6 eV lamp, enabling a wide range of instrument detection in relation to VOC gases. There are 4 detection ranges available on this fixed gas detector; these include 0 – 10 ppm, 0 – 50 ppm, 0 – 1000 ppm and 0 – 3000 ppm.

The Falco TAC utilizes a 10.0 eV lamp on both the pumped TAC and diffused TAC models to identify Total Aromatic Compounds (TACs), which focus on benzene. The Falco TAC is equipped with a detection range of 0 – 50 ppm.

Ultimate Performance

  • Advanced sensor performance dramatically reduces drift & downtime
  • The only VOC detector explicitly designed for extreme weather
  • Typhoon technology stops condensation forming with the PID 

Ultimate Safety

  • Eradicates false readings found with competing PID technology
  • Ex d approved
  • Fitted with long-life lamp for one year continuous use
  • Multi-coloured status display with 20 meter visibility in sunlight

Ultimate Flexibility

  • Diffused unit ideal for detecting VOCs and TACs in areas such as refineries and petrol chemical facilities
  • Falco diffused can be mounted almost everywhere
  • Four detection ranges available
  • Pumped and diffused models available
  • Selectable response factor for varying VOC selection
