It directly measures %O2 and flue temperature, and calculates %CO2, %Excess Air, and combustion efficiency.

What's Included?


  • Automatic Electric Pump with Pause -- Pump works automatically so there's no hand pumping, and techs can pause the pump at any time to save battery lifeSOX3 Combustion Check Oxygen Sensor
  • Field-replaceable Oxygen Sensor -- The SOX3 Oxygen Sensor indicators tells techs when a new sensor is needed. With calibration data stored on the sensor, it can be swapped out in seconds, so there's never a need to send your instrument in for calibration.
  • Hands-free Testing -- The threaded R-cone holds the barrel firmly in the flue, and the strong magnet on the back of the SOX3 holds the instrument firmly to the side of the flue, while the internal electric pump does all the work. Techs simply view the results on the triple line display.
  • Combustion Efficiency -- Quickly calculated and displayed on the screen, the SOX3's combustion efficiency calculation is great measurement to help determine the health of a furnace.
  • Custom Fuels -- Not only does the SOX3 test Natural Gas, Oil #2, and Propane, but it can be quickly, and easily programmed to test any type of fuel. So non-conventional furnaces are just as easy to tune and conventional furnaces.
Like all Fieldpiece products, the SOX3 Combustion Check Tool was designed to help HVACR professionals do more with their tools. From custom fuels to field-replaceable oxygen sensors, the SOX3 can be trusted to measure up for any furnace tuning job.

Great for the Price
Unit is great for the price. It is missing some features that are very helpful during tuning however they clearly state that in the description (CO). A more descriptive manual would be nice as well. Review by / (Posted on 8/27/2014)
