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 C161 offers direct CO2 measurement and features a 30 second start up time.
