 The
Dwyer 480 Vaneometer� Swing Vane Anemometer is
a durable low-priced instrument specifically designed
to simplify the measurement of low air velocities from
25 to 400 feet per minute. OSHA, DPA and other safety
ventilation requirements for spray booths and at fume,
smoke and dust exhaust hoods can now be quickly checked,
even by untrained personnel. Its small size and light
weight - only four ounces make it ideal to carry from
one work station to another. A versatile steel mounting
bracket for continuous monitoring is also included.
The Vanemeter Swing Anemometer is accurate to �5% of
full scale to 100 FPM and �10% from 100 FPM to top
of scale. It has a spirit level to insure accurate
readings and the large scales are easy to read and
visible from both sides. The housing is molded from
tough ABS plastic and easy to clean with soap and water.
The polyester vane can be cleaned with lacquer thinner.
A spare vane is provided.

furnace draft, pressure drop across filters, etc. The 460
gives consistent, accurate results with no tedious calibration.
Rugged plastic for rough daily use. Dual velocity ranges
read 260-1200 and 1000-4000 fpm; pressure ranges from .005-.09
and .05-1.0 inches w.c.
