Sauermann DBM 620 Air Flow Hood - Standard Kit

Also functions as autonomous micromanometer with Pitot tube attachment

The newly redesigned Kimo DBM 620 Air Flow Meter is a multipurpose electronic air balancing instrument primarily used for efficiently taking direct air volume readings from air vents. Hoods are airtight and have a transparent viewing window that allows the user to see through the vent to ensure the hood is in proper position. The measurement grid is attached to the base and measures 24 different points throughout the surface of the flow area. Measurement is performed using a differential pressure sensor calibrated in atmospheric pressure and temperature, and compensated in temperature. Once removed, the measuring unit can be used as a micromanometer.


  • Measuring range from 21 to 2501 CFM
  • Simultaneous display of up to 4 parameters. Choose between:
    • airflow
    • relative humidity
    • atmospheric pressure
    • temperature
    • differential pressure
    • air velocity
  • HOLD function
  • ACR function (Air Change Rate)
  • Automatic airflow direction (extraction or air blast)
  • Automatic averaging or point by point averaging
  • Removable measuring unit (micromanometer function)
  • Long range & Low energy Bluetooth 4.2
  • Switch between hoods quickly and easily
  • Hoods flow straightener Compatible with all air vent types
  • Patented folding frame & space-saving hoods storage
