UEi C161 Residential Combustion Analyzer

Flue Gas Analyzer with Direct CO2 Measurement

The C161 Residential Combustion Analyzer, with EOS Technology, eliminates the number one hassle experienced by HVAC technicians, the cost and down time of replacing the O2 sensor. The EOS award-winning technology for combustion analysis replaces the everyday electro-optical sensor with EOS CO2 technology, lowering the cost of ownership. The C161 offers direct CO2 measurement and features a 30 second start up time. 

Backed by UEi Service+ to give up to 6 years’ warranty, next day recertification, and a reduced cost of ownership. The C161 Residential Combustion Analyzer is easy to use with a rugged design, multiple sensor protections, altitude compensation and a heat exchanger test.
