Residential Combustion Analyzer w/ Case
The C161 Residential Combustion Analyzer equips HVAC/R professionals to install and maintain furnaces and boilers to optimize efficiency and reduce fuel costs.
The C161 combustion analyzer is eligible for UEi Service+, which offers transparent recertification pricing, warranty extensions up to 6 years from the date of purchase, 24-hour turnaround, and free UPS Ground shipping to and from our ISO certified Indianapolis service center.
C161 has two levels of sensor protection; a NOx filtered CO sensor and Low Flow Detection. It also has sensor technology that reduces the cost of ownership, a Heat Exchanger test to check the exchanger integrity, and differential temperature. The C161 comes with high altitude compensation to maintain accurate readings at any altitude, auto-purge shut off, and 8 Pre-programmed fuels including Natural Gas and Propane.
The C161 has a 6-Line display to view readings on one screen, which is a favorite among technicians. The DMM Style dial makes it easy to select the test needed. It also features a water trap to protect the sensor with a check light to remind to look for condensate built-up, a magnetic boot for hands-free operations, and an IR printer port to print to an optional IR thermal printer, making it easy to document test results for later analysis.
