Alnor Rotating Vane Anemometer RVA801

The Alnor RVA801 Rotating Vane Anemometer is designed to measure air velocity and calculate air flow volume with simple, one-button operation. Typical applications include HVAC commissioning, heating and cooling coil analysis, diffuser air flow measurements, fume hoods and indoor air quality tests.

Key Features

  • Reversible 4 inch (100 mm) vane for reading at supply or extract grilles
  • Air flow range 50-6000 ft/min (0.25-30 m/s)
  • Volumetric air flow rate calculation
  • No density correction factors needed
  • Auto averaging of air velocity measurements
  • Compatible with TSI Aircone flow hoods


The Alnor anemometer RVA801 comes with a large 4 inch head for fast and easy measurements of air velocity. Air velocity measurement ranges from 50 to 6000 ft/min and has a stated accuracy of ± 1.0% of reading ± 4 ft/min. The TSI RVA801 also measures temperatures from 40°F to 113°F.

Volumetric flow rate can be calculated by this rotating vane anemometer when the duct dimensions are entered into the display. TSI also offers two Aircone flow hoods that attach to the Alnor Rotating Vane Anemometer RVA801  for faster measurements of air volume. The rectangular hood is 11.2" x 9.2" and the circular hood has a diameter of 7.1".

This TSI rotating vane anemometer is easy to use and is designed for one handed operation. Weighing less than 1 lb it will not be a nuisance to carry around or add to your tool bag. Datalogging is available if need on the Alnor RVA501.

TSI Alnor instruments are Made in the USA and come with a complementary NIST Certificate of Calibration.
