RLGD

Remote Laser Gas Detector
Backed by decade expertise and research on utilization of TDL (Tunable Diode Laser) technology,
the latest RLGD-100 is developed on a well proven technology platform. The RLGD-100, is a
portable detector that allows high-sensitivity real-time detection of methane from a distance.
Methane leaks can be quickly monitored by pointing the laser beam towards the suspected leak,
or along the survey line. It enables easy access to hard-to-reach locations, and provides
protection for operator and industrial applications against a wide range of potential leak sources.

Principle
RLGD-100 employs Tunable Diode Laser (TDL) technology, where laser light beam is projected over
a distance onto a reflective target, a fraction of backscatter is reflected and received by the
transceiver. Methane in the laser path creates a distinct signal in the returned light, which will be
collected and focused onto a detector and converted to an electronic signal. Average methane
density between the detector and target are displayed in ppm.m.
