Rotating Vane Anemometers

RVD	RVA+

The Alnor RVD and RVA+ 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 RVD and RVA+ 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 RVA+ displays temperature and velocity readings simultaneously and has simple button operation. It features an attached swivel head that rotates so the display always faces the operator. The RVD 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.
