The  Rotating Vane RVA801 is a light weight, robust, and simple to use rotating vane anemometer that provides accurate and reliable readings every time.

The RVA801 measures air velocity, air volume and temperature using simple button operation and displays readings in metric or imperial mode from 50–6000 ft/min (0.25–30 m/s).

Product Details

It features an attached swivel head that rotates so the display always faces the operator.

Ideal applications include HVAC commissioning, heating and cooling coil analysis, diffuser and grille measurements, fume hood face velocity, tests, indoor air quality tests and filter face velocity measurements.
