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.
