Crowcon's LaserMethane mini
LaserMethane mini (LMm) is a compact handheld detector for the detection of methane gas at a safe distance (0-100m). Using laser technology, methane leaks are located by pointing the laser beam towards the suspected leak, or along the survey line. This revolutionary technology removes the need to access elevated places, reducing cost and improving the speed of leak detection activities. LMm is ideal for use in industrial, commercial, and research environments, anywhere that methane could be present and in need of locating or monitoring.
LMm is actively replacing handheld detectors that rely on users being within arms’ reach of the potential leak source. This means users don’t need to enter a potentially hazardous location, and therefore improves survey effectiveness. ATEX Intrinsic safety approval means that LMm is suitable for use in Zone 1 and Zone 2 applications.
LMm is easy to operate and requires no maintenance. An automatic self check during start-up ensures consistent performance and reliability every time units are turned on. The green laser guide light is highly visible even under strong sunlight, making locating leaks easier. The Bluetooth option combines the benefit of LMm with additional data storage functions, allowing connection to an Android device using the GasViewer app. Important data including gas level, time, date and location are combined and can then be saved or emailed to a central point.
Measurement principle:
LaserMethane mini detects methane by emitting infrared light and examining the light that is reflected back. Methane gas absorbs
specific frequencies which LMm uses to calculate how much methane is present along the beam path. LMm measures the average
methane gas density along the path of the beam and readings are reported in ppm-m which is the product of the concentration of
the methane cloud (ppm) and the length of the beam path (m). The measurement and guide beams can penetrate some opaque
surfaces, for example glass or perspex, allowing detection of methane through windows in locked rooms.
