Remote Methane Detection
The HEATH Remote Methane Leak Detector (RMLD™) is a highly advanced
technology, capable of detecting methane leaks from a remote distance. The RMLD is
the first of a new generation of leak survey instruments that will greatly improve the
productivity and safety of a walking survey.
With the RMLD it is now possible to survey areas that are hard to reach or not easily
accessible. The RMLD does not have to be within the gas plume because it uses laser
technology known as Tunable Diode Laser Absorption Spectroscopy. As the laser passes
through a gas plume, the methane absorbs a portion of the light, which the RMLD then
detects. This technology makes it possible to detect leaks along the sight line without
always having to walk the full length of the service line.
