The Fieldpiece SOX3 Combustion Check is a great tool to easily tune furnaces when a full combustion analysis isn't necessary. Designed specifically for HVACR pros, the Fieldpiece SOX-3 Combustion Check provides all the essential measurements needed to tune most combustion.
The Fieldpiece SOX-3 measures %O2 and flue temperature, and calculates %CO2, %Excess Air, and combustion efficiency.
The electric Pump works automatically so there's no hand pumping, and techs can pause the pump at any time to save battery life.
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. 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. Quickly calculated and displayed on the screen, the SOX3's combustion efficiency calculation is great measurement to help determine the health of a furnace. 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.
