REED 8906 Vane Thermo-Anemometer, CFM (Air Volume)


This professional grade thermo-anemometer provides accurate air velocity, air volume and air temperature measurements. The 8906 is capable of taking continuous air velocity averaging measurements for up to 2 hours and features a low friction rotary vane for improved accuracy and the ability to simultaneous display air velocity and temperature on the large dual LCD display.


  • Measures fpm, m/s, kph, mph and knots
  • Dual LCD display simultaneously displays air velocity and air temperature
  • Calculates air volume (CFM)
  • Basic accuracy of ±2%
  • Min/Max/Avg and Data Hold Functions
  • Low battery indicator and auto shut off
