ALNOR INSTRUMENTS

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.

Features and Benefits

• Measures velocity and temperature
• Reversible 100 mm head allows readings at supply and extract grilles
• Calculates volumetric flow rate
• Compatible with Aircone Flow Hoods
• Comes with a certificate of calibration
