Kanomax Rotating Vane Anemometer 6820

The Anemomaster™ Rotating Vane Anemometer – 6820 Series offers a range of highly accurate airflow measuring devices. Models include industrial grade enclosure and probe. They automatically calculate volume flow in CFM (cubic feet per minute) or CMH (cubic meters per hour). When measuring ducts dimensions are stored in memory on turn-off and do not need to be re-entered. These vane anemometers can store up to 10 different commonly-used duct sizes for quick, convenient readings in the field. Models also available for airflow/temperature and airflow/temperature/humidity.


  • High accuracy: +/- 1.0 % of reading
  • 40 FPM of air velocity sensitivity
  • Temp. Measurements from -22 to 212F
  • Three output options available:
    • Analog voltage
    • USB
    • RS232
  • Rugged metal probe and vane
  • This is a high quality instrument which provides accurate air velocity and volume flow measurements in the harshest environments
  • The user can easily enter the size of the duct opening and the 6822 automatically calculates the volume flow rate from the duct
  • The duct size is automatically stored in memory on turn-off and up to 10 unique duct sizes can be stored and recalled for frequent use
  • Includes NIST-traceable calibration certificate
  • HVAC Ventilation and Balancing
  • Laboratory Control
  • IAQ Investigation
  • Industrial Hygiene Quality Control
