AAV3 - Air Velocity and Temperature
Accessory Head

Easy to Use Vane Anemometer

Estimate CFM
Large vane covers most of register’s free area
Displays average measurement and real-time

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, ºF (degrees Fahrenheit) or ºC (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.  

The AAV3 Anemometer Air Velocity and Temperature Accessory offers several features and benefits to field technicians:

  •   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 minutes (may be disabled).

Connect to most Fieldpiece meters with ADLS2 Lead Set, AHDL1 Handle with fly leads or use our wireless kit - EH4W. 

Fits straight onto your HS26, HS33 HS35 or HS36 Stick Meters.
