About This Product

The UEi C161 is a residential combustion analyzer featuring EOS (Electro-Optical Sensor) technology that eliminates costly O2 sensor replacements by using optical CO2 measurement instead. It measures CO (0-2000 ppm), CO2 (0-20%), O2 (0-21%), and flue/inlet temperatures up to 1112F with 8 preprogrammed fuels, 30-second startup, and built-in heat exchanger test. NOx-filtered CO sensor and low-flow detection provide sensor protection, while the UEi Service+ program offers up to 10-year warranty coverage.
