This robust and reliable diffusion-based point-type infrared (IR) detector is a good choice for monitoring CO₂ suppression cylinder storage and skids for CO₂ detection in enhanced oil recovery sites. It provides continuous monitoring of CO2 gas concentrations in the range of 0-2%/volume (0-20000 ppm). All units are powered from 24 Vdc, and are furnished with an onboard “status indication” LED, an internal magnetic calibration switch and an external calibration line for use with the optional PIRTB remote calibration termination box. The Eclipse CO2 detector is ideal for use in harsh outdoor environments and is certified for use in Class I, Division 1 (CSA), and Zone 1 (ATEX/IECEx) hazardous areas. It can be used as a stand-alone detector, or as part of a larger facility protection system.
