The infrared beam width is about 22” at 100 feet. It is important to note that the laser beam “footprint”
width and distance increases as the distance increases. This is why it is much easier to detect leaks from a
distance of 10 to 15 feet and beyond.
NOTE: There is always a small amount of methane in the air. This natural methane background is also
measured by the RMLD-CS. The PPM-M reading will then increase as the scanning distance increases.
NOTE: The nature of a gas plume is highly variable. The above illustrations are intended to convey the basic
theory. Some leaks may have a high surface concentration with little to no measurable plume above the
surface.
