UEI Residential Combustion Meter - Measure O2 Only

The UEI C160 Residential Combustion Meter is a focused, easy to use analyzer built for technicians who need a fast, reliable oxygen reading when servicing residential heating equipment. Measuring O2 is a foundational step in confirming that a furnace, boiler, or water heater is burning fuel efficiently and safely, and the C160 delivers that measurement in a simple, affordable package. Proper combustion depends on the right balance of fuel and air, and the oxygen level in the flue gases is a key indicator of that balance. Too much or too little tells the technician the burner needs adjustment, helping prevent wasted fuel, incomplete combustion, and unsafe operating conditions. The C160 keeps the workflow straightforward so you can take a reading, make an adjustment, and verify the result quickly on a service call. Backed by UEI's more than 50 years designing test and measurement tools for the trades, the C160 is a practical entry point into combustion analysis for residential service work. For HVAC technicians who want a dependable O2 meter without the complexity and cost of a full commercial analyzer, the C160 is a smart choice.
