Manometer Accessory - AMN2

The AMN2 is a portable dual port manometer accessory head for use with our modular multimeters (DMMs) and instruments. Measures gas pressure with a resolution for static pressure measurements. The AMN2 includes a zero adjust and the Auto Power-Off (APO) function conserves battery life. Disable APO for data logging. The AMN2 measures pressure between -60inWC and 60inWC (inches of water column). Take static pressure measurements using the resolution mode of 0.01inWC. Special purpose static pressure instruments are on the market with better accuracy and temperature compensation, but they typically cost much more than the AMN2.

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.

Digital Sling Psychrometer Accessory - ARH4

The Fieldpiece model ARH4 Digital Sling Psychrometer and Hygrometer Accessory Head measures both relative humidity and ambient air temperature. It calculates dew point and wet bulb. It’s great for calculating target superheat as well as logging %RH, temp, WB or DP over time. The head converts %RH, ambient temperature, dew point temperature, and wet bulb temperature to a voltage at a rate of 1 %RH or degree to 1mVDC and your reading is displayed on your meter. The ARH4 snaps directly onto Fieldpiece stick meters, data logger, electronic handles and adapters.

Superheat Accessory for Air Conditioning - ASH3

The Fieldpiece Superheat Accessory for Air Conditioning – model ASH3 measures suction line, or low side, line temperature and pressure and calculates ACTUAL superheat in real time. Use it to get ACTUAL superheat on R-22 and R-410A fixed orifice systems. On systems regulated with a TXV / TEV you’ll want to look at our ASX14, ASX24 and SSX34 superheat and subcooling instruments. Use the “T” fitting to charge to actual superheat by putting the ASH3 in-line between your refrigerant bottle and the system.

Superheat and Subcooling Accessory for Air Conditioning - ASX14

The Fieldpiece Superheat and Subcooling Accessory for Air Conditioning, model ASX14, measures suction line, or low side, line temperature and pressure.
