The IR5500 Open Path Gas Detector is billed as the first open-path detector to meet agency performance requirements on both the LEL meter and ppm meter scales.
With a split range scale, the IR5500 is certified for operation at -55ºC and is also certified to FM approvals, EN, and IECEx performance standards. Designed to provide continuous monitoring of combustible gas concentrations, the IR5500 system consists of an IR source and receiver, which monitors for methane in both the 0 to 5,000 ppm meter and 0 to 5 LEL meter range. 0 to 2,000 ppm meter and 0 to 1 LEL meter scales are also available for monitoring propane. The IR5500 design includes single-beam detection to improve accuracy and reduce drift, as well as continuous self-check monitoring for fail-to-safe operation.
