Pergam - Model LMS - Open Path Gas Detector - Brochure

The stationary gas detector LMS Open-Path is infrared methane sensor with open optical path technology. Capable of providing continuous control up to explosive concentrations of methane vapors at a distance of up to 1 km. The remote gas analyzer is designed to detect methane in the atmospheric air and automatically signal the excess of its concentration. The device measures the intensity of infrared radiation when it passes through an environment in which methane vapor is present. Unlike similar gas analyzers made using open optical path technology, in the LMS Open-Path both the transmitter and the infrared receiver are installed in one unit, and a retroreflector is used to reflect the signal.
