What is a LaserMethane® Detector?

The LaserMethane® is an unique portable device enabling remote detection of methane gas.

The LaserMethane® utilizes infrared absorption spectrophotometry of methane gas. The volume of methane gas is measured by emitting a specific laser light towards a measurement point then detecting some of the scattered light from the target. The measured gas volume is expressed as methane column density (ppmEm), methane density (ppm) multiplied by the thickness (meter).


Features of LaserMethane®



Comparison with other technologies


(1)Fast Response and Sensitivity

Instant detection is virtually possible with the LaserMethane® (only 0.1 second). The sensitivity is 10ppm-m (10ppm x range length1m).

(2)Excellent Selectivity

The LaserMethane® detects only methane gas because the laserfs wavelength is chosen such that only methane gas absorbs the light; therefore false detection of other gases is avoided perfectly.

(3)Remote Detection

Absorption rate of methane can be measured from a distance, which enables detection of methane gas leakages at places where conventional technologies cannot be applied easily. Such locations include high locations such as pipes on ceilings and narrow places.

(4)Downsizing and Easy Operation

The LaserMethane® detector is so small and light that an operator can carry and conduct inspection without additional help. Operation is very easy because only two buttons are normally used (power switch and measurement trigger).

(5)Detection over windows

The device can work over windows since the laser beam easily penetrates through glass, as the infrared beam is not absorbed by silica significantly.
