Uei Test Instruments UEI-C161 Flue Gas Combustion Analyzer

Product Description

The UEI TEST INSTRUMENTS UEI-C161 is a residential flue gas combustion analyzer designed for technicians installing and servicing gas appliances. It measures carbon monoxide, oxygen, excess air, and flue gas temperature to deliver the essential data needed for combustion analysis and appliance tuning. The unit includes a heat exchanger test function and differential temperature measurement, making it practical for both installation checkout and routine maintenance. Altitude compensation is built in, and multiple sensor protection features help extend sensor life in the field. Licensed HVAC technicians and combustion service techs are the primary installers and users.

The UEI-C161 is suited for residential gas appliance applications including furnaces, boilers, and water heaters. It is built to handle the demands of field service with a rugged housing and an interface designed for quick, single-technician operation. The analyzer calculates combustion efficiency and related parameters directly, reducing the need for manual calculations on the job. An optional printer accessory allows on-site report printing for service documentation or homeowner records.

• Altitude compensation for accurate readings at varying elevations
• Multiple sensor protection features to extend sensor service life
• Compatible with optional printer for on-site report output

Compatibility

Designed for use on residential gas appliances including furnaces, boilers, and water heaters where flue gas combustion analysis is required.

Installation Notes

The UEI-C161 is a handheld field instrument used by licensed HVAC technicians and combustion service professionals. Before sampling flue gases, ensure the appliance is operating at a stable steady-state condition and that all access panels are in place per the manufacturer's guidelines. Follow local codes and appliance manufacturer procedures when inserting the probe into the flue or heat exchanger test port. Allow the analyzer to purge and zero out in fresh air before and after each test session to protect sensor accuracy.
