Fieldpiece SOX3 Combustion Check New with Hard Case

The 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 SOX3 provides all the essential measurements needed to Tune most combustion equipment. It directly measures percent O2 and flue temperature, and calculates percent CO2, percent excess air, and combustion efficiency. made in United States. Manufactured by Fieldpiece instruments Inc.

• Automatic electric pump with pause - pump works automatically so there's not hand pumping, and techs can pause the pump water any time to save battery life
• Fieldpiece
• Measures flue temp and oxygen percentage. Calculates carbon di oxide percentage and EA percentage
• 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
• 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
