portable open-path tdl analyser

The GasFinder3 Laser Gas monitor is used for the continuous measurement of GHG emissions (CO2 and CH4), and is particularly suitable for monitoring landfill sites.

A lightweight and portable unit, the GasFinder OP provides information on the average concentration of gas in the measurement path. The open path gas detection laser technique works by emitting an invisible laser beam that is sensitive only to the gas of interest. The Reflector Array returns the laser beam to the detector which then calculates the concentration of the gas in the measurement path.

Featuring fast response, self-calibration, no moving parts or consumables, the monitor can also be combined with Radial Plume Mapping (RPM) software to generate concentration maps and flux estimates.

Combines both ease of use with continuously acquired data, ready for analysis.


  • Continuous and instant results
  • Simple data collection and interpretation
  • Can handle the coldest winters and hottest summers
  • One second response time
  • No interference with other gases
