Fieldpiece SOX2 Standalone Combustion Check Meter

The SOX2 Standalone Combustion Check Meter checks for % Oxygen, % Carbon Dioxide, Flue Temp, and % Excess Air.
The SOX2 allows you to easily calibrate combustion equipment such as boilers or a furnace to the manufacturer's specified Excess Air %, CO2%, or O2%. Tuning the Excess Air, CO2, O2 stack temperature and temperature rise to match the appliance manufacturer's specifications will increase efficiency and help maximize performance and life expectancy of the equipment. Tuning typically involves adjusting the air/fuel ratio.

The SOX2 combustion check offers several features and benefits to field technicians:

• Measurements for three most common fuel types - Natural gas, Propane and Oil #2.
• Simple operation.
• Gives you the tests you're looking for to get the job done quickly and efficiently.
• Doesn't include a lot of extra tests, calculations and buttons you don't need and that get in the way.
• Fraction of the cost of full-function combustion analyzers. (Suggested trade only $239)
• Comes with everything you need to measure against manufacturer's specs. No extras to buy. (See What's Included)
• APO (Auto power off).
• Dual-display. Cycle through parameters. Temperature is always displayed.
• Four display options allow you to find the data you need. Minimum, maximum, real time and hold.
• Bright blue backlight for testing in dark areas.
• Thermocouple calibration pot on front-face of meter for quick adjustments.
• Quick and easy filter replacement on hand pump.
• Magnetic hanger so you can hang meter while taking flue gas samples.
• Rugged rubber boot stands up to the day to day punishment dished out during field service.
• Ergonomic shape.
