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 life
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 no 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
Measures flue temp and %O2
Calculates %CO2, %EA, and combustion efficiency
Hands-free testing with magnet, R-cone, and automatic pump
Programmable for custom fuel types
Fast, easy, furnace tuning
