The UEI C165+NOILN Residential/Commercial Combustion Analyzer for Oil-Fired Appliances with NOx Sensor equips HVAC/R professionals to install and maintain furnaces and boilers to optimize efficiency and reduce fuel costs.

Backed by UEi Service+ to give up to 10 years’ warranty, next day recertification, and a reduced cost of ownership. The C165+NOILN Residential/Commercial Combustion Analyzer is easy to use with a rugged design, multiple sensor protections, altitude compensation and differential pressure. And an installed NOx sensor. Prints to optional printer and wireless App. The new LINK feature connects the included wireless pipe clamp temperature probes and other optional probes to the C165+. Essential information for installing and maintaining furnaces and boilers all in one device. With included Smoke Pump Test Kit. The C165+NOILN has an installed Nitric Oxide (NO) sensor. C165+NOILN 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+NOILN LINK also connects the optional DTHA2 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+NOILN 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+NOILN 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+NOILN has a 6-Line display to view readings on one screen, which is a favorite among technicians. The Digital Multimeter 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 an optional IR thermal printer, making it easy to document test results for later analysis.
