This combines full ATEX approval with a new green laser guide-light for improved visibility across a range of conditions, including in strong sunlight.

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.

Crowcon said that, unlike conventional methane detection methods, which must be in direct contact with the gas in order to detect it, LMm enables remote detection of gas leaks. With a range of 30m in standard mode, or 100m with a reflector, LMm enables operators to detect methane gas from a safe distance.

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 more safely.

The typical response time of LMm is just 0.1 seconds, minimising the time that operators are exposed to a potentially hazardous environment.
