PointWatch Eclipse® Infrared CO2 Gas Detector


Specially engineered to detect CO2

The PointWatch Eclipse® Infrared Carbon Dioxide (CO2) gas detector detects carbon dioxide in harsh environments either as a stand-alone detector or as part of a total facility safety system. 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. 


  • On-board tri-color LEDs for local alarm and fault annunciation
  • Immune to damage from exposure to constant background gases or high gas concentrations
  • Routine calibration not required
  • Life-safety control functions (providing output via 4-20 mA HART and relays)
  • Ancillary communication options (communicating via HART or RS-485 Modbus)
  • Weather baffle with hydrophobic filter option combined with heated sapphire optics reduces nuisance faults from rain and condensation in harsh environments
