The UEI C157 EAGLE 3X eXtended Life Combustion & System Analyzer with Case & Probe

The newly redesigned Eagle 3X Combustion System Analyzer eliminates the number one hassle for combustion contractors; the annual replacement and calibration of the O2 sensor. By replacing the electro chemical O2 sensor with the EOS Technology CO2 sensor, the EAGLE 3X now takes direct CO2 measurements and calculates the O2 level. This lowers the cost of ownership by doing away with the annual replacements of the O2 sensor and reducing calibration drifting typically found with standard electro-chemical sensors. The EOS Technology sensor is warranted for 5 years and has an unmatched industry-leading life expectancy of 10 years .


  • Measures: Differential flue temperature, Carbon Dioxide CO2, flue & ambient carbon monoxide CO, Nitric Oxide NOx & Hi-Res Differential Pressure
  • Calculates: Oxygen O2, gross/net efficiency, excess air, & CO air free
  • High level CO alarm
  • CO data logger
  • Heat exchanger test
  • Built-in Worklight
  • Large 4 line backlit LCD display
  • 179 memory positions
  • User customizable parameters view
  • Individual report printouts
  • Unique DMM style rotary selector
  • Protective boot with integral magnet
  • Real time clock with date & time stamp
  • CO readings to 1ppm
  • Infrared printer port
  • Battery level indicator
  • Field replaceable sensors (USA only)
  • Gas Zero (Fresh Air Zero) - Is a reset procedure to maintain accurate readings
    from the EOS sensor. This procedure compensates for any change in ambient
    conditions that may impact the readings.
