Combustion Meters
Fieldpiece Instruments offers a variety of combustion meters for HVAC/R field service. Whether you’re looking to perform a quick combustion check or a carbon monoxide walk-around or flue test, or a full -n combustion analysis, you’ll find it here. This product category includes standalone test instruments, accessory head instruments and analyzers that allow you to perform combustion tests and analysis.


The ACM3 has a fast electrochemical sensor specific to carbon monoxide or CO. It measures CO in parts per million (0-1000 ppm, 2000 ppm max 5 min. exposure time)

Carbon Monoxide Detector Accessory - ACM3

The ACM3 is a carbon monoxide detector (CO detector) accessory head for use with our modular instruments that measures CO in parts per million (ppm). Its electrochemical sensor is fast enough for walk-around tests. Features and benefits include: Advanced, three-pin sensor that measures 0 to 1000 ppm CO; Calibrate / Zero ACM3 to ambient quickly with the zero calibration pot under the grey rubber strip; Auto Power-Off (APO); Use optional pump (AOXP2) for remote / flue gas testing.

The AOX2 Combustion Check head gives technicians all of the test parameters they need for everyday combustion testing without all of the costly extras they don't need. Measures % O2 and Flue Temp, Calculates % CO2 for Oil and Gas equipment.

Combustion Check Accessory - AOX2

The AOX2 is combustion check accessory head that measures % O2 (percent oxygen) and flue gas temperature. It calculates % CO2 (percent carbon dioxide) for two fuel types: gas and oil. Technicians use the AOX2 to sample flue gas on serviced or newly installed equipment. It eliminates the costly, extra tests found on full-function combustions analyzers that technicians often don’t use or need. Match your results to specifications on the data plate or in the manufacturer’s manual to quickly tune furnaces, boilers and more.

The SOX2 Combustion Check gives technicians all of the test parameters they need for everyday combustion testing without all of the costly extras they don't need. Measures %O2 and Flue Temp, Calculates %CO2 and % Excess Air.

Combustion Check Meter - SOX2

The SOX2 Combustion Check meter measures percent oxygen (% O2) and flue temperature and calculates percent carbon dioxide (% CO2) and percent excess air (% EA) for oil, natural gas and propane fuel-burning appliances. It's designed for everyday combustion testing and tuning, without all of the costly extras found on full-function combustion analyzers – extras technicians tell us they don't need. Easily tune combustion equipment such as boilers and furnaces to the manufacturer’s specifications to increase efficiency and to maximize performance and life expectancy of the equipment.
