The newly redesigned Eagle 2X 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 2X 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!
