• Works with any Fieldpiece expandable instrument or handle or any DMM with mVDC ranges and our detachable leads Measures air velocity and measures air temperature Measure in hard to reach areas using detachable test leads Display readings smoothly in average mode or switch to real-time measurement Low battery indicator Auto power-off after 10 min (may be disabled) Estimate CFM Large vane covers most of register's free area Displays average measurement and real-time Red LED for low battery indication 1 mVDC/unit of measure except ft/min greater than 2000 At greater than 2000 ft/min the green light lights up and conversion rate changes to 1 mVDC/100 ft/min (multiply LCDX100) conversion +/- 3% full scale + 1 digit air velocity accuracy +/- 1 deg F (32 - 110 deg F, +/- 2 deg F (-4 to 32 deg F and 110 - 140 deg F) temperature accuracy Displays parameters directly on DMM set on mVDC scale Ball bearing moving vane Works like all the other Fieldpiece accessory heads 32 - 122 deg F temperature AAV3 air velocity and temperature accessory, 9 V alkaline battery (installed), operator's manual

The AAV3 is an anemometer accessory head for use with our modular instruments that measures air velocity and temperature in English or Metric units: ft/min, m/s, MPH, KM/hr, deg F (degrees Fahrenheit) or deg C (degrees Celsius). Multiply your air velocity by the register's free area to estimate CFM or diagnose duct blockages and quickly check the airflow balance in a conditioned space. Use with our DL3 Data Logger to track airflow or temperature over time. Features average and real time testing modes.
