Boreal GasFinder3-OP

The GasFinder3-OP is a field deployable Open-Path Tunable Diode Laser (OP-TDL) based gas analyzer system that is primarily used for:

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

This technology is also most commonly referred to as Open Path Gas Detection (OPGD) or Line of Sight (LOS).

This particular technology is ideal for detecting or monitoring for a number of different Toxic, Combustible, Hazardous, or Greenhouse Gases.
