Rotating Vane Anemometers
The Alnor RVA501 and RVA801 Rotating Vane Anemometers measure air velocity,
air volume, and temperature in English or metric units. The 4-inch (100mm)
head automatically averages velocity and volume readings, making the RVA501
and RVA801 essential tools for measuring unevenly distributed or fluctuating
flows through heating and cooling coils, diffusers, grilles, and filters.
Sweep mode quickly and reliably provides one averaged reading of velocity
or volume over a large measurement area.
The RVA801 measures velocity and temperature using simple button operation. It features an attached swivel head that
rotates so the display always faces the operator. The RVA501 Rotating Vane
Anemometer has a detachable 4-inch (100mm) head for taking measurements
in tight spaces. Its telescoping probe provides safe access to hard-to-reach
locations and its data logging capability allows storage of 999 readings.
