Compressed air monitoring system for verification of Carbon Monoxide (CO) with electrochemical principle of low maintenance and long life of use, Oxygen (O2) and dew point. It is a complete and portable system ideal to verify the degree of purity and breathable air conditions of virtually any compressor or system:

  • Electrochemical sensor for measurement of Carbon Monoxide (CO) in the range of 0-99 ppm
  • Electrochemical sensor for oxygen measurement (O2) in the range of 0-25% Vol.
  • Dew point from -112 ° F to 68 ° F
  • Optional three-stage efficient filtration panel for removal of particulate matter, oil vapors and hydrocarbons from the air line
  • LCD display
  • Audible and visual alarm set at 5 and 10 ppm CO, 19.5% and 23.5% Oxygen Vol, 4 ° F Dew Point
  • Housing in NEMA 4X high strength
  • High pressure connection 30 to 145 psi
  • NO / NC relays depending on the model
  • Operation through 110 VAC or 12 - 24 VDC for up to 24 hours with 2 hour charge cycle
