Portable methane detector goes green for improved visibility in ATEX-rated environments

The use of infrared laser absorption spectroscopy enhances safety by allowing operators to remain at a safe distance from potentially dangerous leaks and provides an almost instantaneous response in the presence of methane gas.

The unit has a range of 30m in standard mode, or 100m with a reflector. As the laser beam can penetrate some transparent surfaces, such as glass, LMm also detects methane through a window allowing closed premises and confined spaces to be checked faster and safely.

LMm is ATEX approved for use in explosive environments, including remote-monitoring applications such as closed or confined spaces, above-ground riser pipes, and pressure-regulating stations.

The typical response time of LMm is just 0.1 seconds, making it suitable for quickly scanning an area for a suspected leak and further minimising the time that operators are exposed to a potentially hazardous environment.

LMm uses infrared laser absorption spectroscopy which measures the specific wavelength of infrared light that is absorbed by methane gas. This provides accuracy and specificity for operators by making LMm immune to other gases and eliminating the risk of false alerts.

LMm performs a shelf check and an internal calibration at start up. This requires no training and ensures readings are always accurate and reliable.LMm doesn’t need regular recalibration.
