Landfill and biogas monitoring solutions including surface emissions, well field monitoring and fixed position gas monitoring.
FAU-TDL
The FAU-TDL uses Tunable Diode Laser Technology to enable accurate and reliable measurements with no drift over time or cross gas sensitivity. This analyzer is the most reliable and cost effective solution for Carbon Credit verification and Green House Gas (GHG) reporting. The development of ECOTEC’s FAU-TDL is the culmination of research by NASA’s Jet Propulsion Laboratory for use on Mars. The optical system uses a laser to produce a specific wavelength of light tuned to an absorption line, the known light frequency of the target gas. This technique produces an analyzer with a fast response speed, where the laser light stimulates vibrations and rotation in the molecule, resulting in energy absorption and enabling the sensing of gas.
