The GasFinder3-DC and associated measurement heads are a field deployable Open-Path Tunable Diode Laser (OP-TDL) based gas analyser system that is primarily used for:

  • Leak Detection: provides immediate and unambiguous detection of fugitive gas releases in safety applications
  • Ambient Monitoring: continuously monitors gas concentrations over open area and/or point sources for environmental monitoring applications.

How it works

  • This system has the ability to monitor one (1) or two (2) measurement heads with one (1) GasFinder3-DC analyser.
  • Measurement Head Options: OPX Head (Open-Path Head), RPX Probe (Remote Point Probe), SDX Probe (Stack/Duct Probe), EMX Cell (Extractive Measurement Cell), ILX Probe (In-line Probe), and IPX Probe (Insertible Probe).
  • Boreal’s OP-TDL technology counts every target gas molecule in the measurement path to give a path integrated ppm-m concentration or path average ppm concentration.
  • Boreal Laser has a patented internal reference cell that does not require routine intervention or zero/span gas to eliminate drift as this is done automatically and once a minute
  • This analyser utilises a mono-static configuration with the analyser being transceiver and having a passive retro-reflector returning the laser light
  • Measure only the target has and all of the target gas. Boreal analysers do not suffer from cross interference and are not confused by other gases present or are affected by humidity.
  • Cannot be poisoned or mechanically over ranged

  • No interference with other gases

  • No memory effects as each sample is independent from the last

  • Data collection and interpretation is simple and intuitive

  • Built for ambient winter and summer conditions

  • Minimal maintenance and intervention

  • Sophisticated self-diagnostics and data validation

  • Can provide an independent sample or reading every second

  • Free and unlimited phone and email support
