UEi C157 Eagle 3X Combustion Analyzer

The UEi C157 Eagle 3X Combustion Analyzer eliminates a significant hassle experienced by HVAC contractors who use combustion analyzers - the annual cost and associated down time of replacing the O2 sensor. With the C157, the electro-chemical O2 sensor is replaced with the EOS Technology CO2 sensor which calculates the O2 level based on the CO2 concentration. This CO2 sensor has no physical contact with the gas, so there is no deterioration of the sensor over time. The exclusive CO2 sensor has a an unmatched industry-leading life expectancy of 10 years. The Eagle 3X also offers an Xtended Life carbon monoxide sensor which has a life expectancy of 5 years, a lengthy life in terms of CO sensors. Reducing the sensor replacement frequency helps to minimize the user's cost of ownership to just the CO sensor calibration. The sensor can detect CO levels as low as 1 ppm.


The UEi C157 Eagle 3X Combustion Analyzer measures carbon dioxide (CO2), carbon monoxide (CO), inlet and flue temperatures, differential pressures and nitric oxide (NO). From these measurements the following can be calculated; oxygen (O2), net temperature, combustion efficiency, excess air, differential temperature (T1-T2) and differential pressure (P1-P2). The pre-programmed fuels include, natural gas, propane, heavy and light oil, bio fuel and wood.
