About the Fieldpiece AOX2

The FieldPiece AOX2 Combustion Check Accessory. This combustion check head measures the percentage of oxygen and flue temperature, and calculates the precent of carbon dioxide. It's an affordable alternative to a full-function combustion analyzer, and can be used with just about any multimeter. It features a quick and easy filter replacement on the included AOXP2 hand pump, and gives you a thermocouple calibration pot on the front-face of the meter for quick adjustments. It also comes with an auto power off function and everything you'll need to measure against the manufacturer's specs. This package includes the following pieces: a Combustion Check MEter (AOX2), a Flue Aspirator Pump (AOXP2), a hi-temp K-type thermocouple, a 9V alkaline battery, and an operator's manual.
