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.

Fieldpiece Anemometer Head, For Use With: Vane Anemometer, +/-0.1 deg F Resolution, Yellow

• 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
