Alnor RVA+ Digital Vane Anemometer
A New Twist in Air Flow Measurement

The RVA+ from Alnor Instruments is a rotating vane instrument that measures air velocity (in fpm or mph) and volume (cfm). This unique design is useful for anyone measuring velocity from grilles or exhaust flow into laboratory fume hoods. The RVA+ features a 4" head which swivels so that the LCD display always faces the operator. Its simple button operation allows for one touch or continuous averaging.

Specifications:

Measurement range:
Velocity: 50-6,000 fpm (0.25-30.0 m/s)

Volume: actual range is a function of maximum velocity times area input (display will show values up to 5400 x1000 cfm or
9,174 x1000 m³/h).

Area Input: 0.08-900 ft² (0.007 to 90m²)

Temperature: 32-140°F (0-60°C)

Display Resolution:

Velocity: 1 fpm (0.01 m/s)

Temperature: 1°F or 1°C

Accuracy:
Velocity: ±1% of reading + 4 fpm
Temperature: ±1°F or 1°C
