Remote Handheld Methane Leak Detection technology from HMA INSTRUMENTATION allows end users to survey difficult-to-reach areas easily, or those not easily accessible, such as fenced-off areas. This results in significant occupational and workplace health and safety benefits, as the end user does not have to be within the gas plume in order to detect a leak.
Using tunable laser diode (TLDAS) technology, the Remote Handheld Methane Leak Detection from HMA INSTRUMENTATION utilises a laser tuned to measure methane transmitted only through a gas plume. The methane absorbs a portion of the light that, upon reflection, is detected by the handheld unit. The latter incorporates a green laser pointer for visual indication of direction. It is powered for up to eight hours by a lithium-ion battery within the handle.
The RLGD-100 employs Tunable Diode Laser Adsorption Spectroscopy (TDLAS) technology from HMA INSTRUMENTATION is where laser light beam is projected over a distance onto a reflective target, and 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 is collected and focused onto a detector, and converted to an electronic signal. Average methane density between the detector and target is calculated and displayed in ppm·m.
Key features of the RLGD-100, which employs Tunable Diode Laser Adsorption Spectroscopy (TDLAS) technology from HMA INSTRUMENTATION, is that it can locate methane up to 30 m away, has an ultra-fast response down to 0.1 s, no cross interference from other gases, self-diagnostics and automatic calibration, easy to operate and maintenance-free, continuous operation for up to eight hours, visual and audible alarms, a user-friendly LCD display, wireless data logging, and a lithium-ion battery.
