- 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.
