Fieldpiece SOX3 Combustion Checker with Auto Pump
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.
The SOX3 Combustion Check Oxygen Sensor is a professional tool designed to efficiently tune furnaces when a full combustion analysis isn't necessary. Engineered specifically for HVACR professionals, the SOX3 delivers all 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 maximize productivity with their tools. From custom fuels to field-replaceable oxygen sensors, the SOX3 can be trusted to deliver accurate results for any furnace tuning job.
- Automatic Electric Pump with Pause: Pump operates automatically eliminating hand pumping, with pause function available at any time to conserve battery life
- Field-replaceable Oxygen Sensor: The SOX3 Oxygen Sensor indicator alerts technicians when a new sensor is needed. With calibration data stored directly on the sensor, replacement takes seconds with no need to send the instrument in for calibration
- Hands-free Testing: The threaded R-cone securely holds the barrel in the flue, while the strong magnet on the back of the SOX3 firmly attaches the instrument to the side of the flue. The internal electric pump handles all the work while technicians simply view results on the triple-line display
- Combustion Efficiency: Quickly calculated and displayed on screen, the SOX3's combustion efficiency calculation provides an excellent measurement to help determine furnace health
- Custom Fuels: Tests Natural Gas, Oil #2, and Propane out of the box, and can be quickly and easily programmed to test any fuel type. Non-conventional furnaces are just as easy to tune as conventional systems
