Residential/Commercial Combustion Analyzer Kit w/ NOx Sensor/Printer
The C165+ Commercial Combustion Analyzer equips HVAC/R professionals to install and maintain furnaces and boilers to optimize efficiency and reduce fuel costs.

The C165+ 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.

The C165+ has an installed Nitric Oxide (NO) sensor. C165+ enables a LINK feature to connect to wireless probes. The LINK feature connects to the 2 wireless temperature pipe clamps (WPC2), which can be used to compare flow and return temperatures on a boiler. C165+ LINK also connects the optional DTHA2 (sold separately) to measure air flow. Contractors can use the Room CO test to take snap shots of ambient CO readings to view trending CO levels. C165+ has four levels of sensor protection; an H2 compensated 10,000 ppm CO sensor, CO over-range purge pump, a NOx filtered CO sensor, and Low Flow Detection to protect the CO sensor. It offers differential pressure and has wireless capabilities to a Printer App for compatible iOS and Android devices. It also has sensor technology that reduces the cost of ownership. It features a Heat Exchanger test to check the exchanger integrity and differential temperature. The C165+ comes with High Altitude compensation to maintain accurate readings, an auto-purge shut off, and 8 Pre-programmed fuels including Natural Gas and Propane.

The C165+ 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 the IR thermal printer, making it easy to document test results for later analysis.
