CE Certified, C-Tick (N22675), RoHS Compliant, WEEE Listed

• 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 temperature 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 69.8 mm W x 45 mm H x 211.7 mm D dimension Auto off after 15 min 32 - 122 deg F operating temperature, less than 75% RH Four digit liquid crystal display(LCD) with maximum reading of 9999 SOX3 combustion check, RSOX3 barrel and thermocouple handle, RCONE2 threaded barrel lock, RAOX9 filter accessory kit, padded, blow-molded case With auto pump

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