The Kestrel 1000 Anemometer
DESCRIPTION
The Kestrel 1000 Pocket Anemometer is a small electronic rotating vane type of anemometer
that can be easily carried in a pocket.
It uses high precision jewel bearings and a light
weight impeller to provide accurate wind and air flow measurements even at low speeds.
The impeller assembly is replaceable by the user in the case of damage.
Low power microprocessor technology is used to provide speed, maximum speed, average speed
and units selection; functions normally only found on more expensive instruments.
The liquid crystal display has large 10mm high digits for clear readout.
Power is from an easily replaceable standard lithium coin type cell that will typically
give up to 400 hours of operation.
The instrument automatically switches off if no keys
are pressed for 30 minutes
The Kestrel Pocket Anemometer is made from high impact injection moulded plastic and
corrosion resistant materials with the electronics fully sealed.
It will float if
accidentally dropped into water. There is a hard cover for protection when not in use and
a lanyard is provided for added security.
OPERATION
Two buttons on the front of the instrument mean operation is extremely simple. One button
(ON) is used to switch on/off and the other (MODE) is used to select the display of
current, maximum or average air speed.
Holding the ON button down and pressing the MODE button selects the required units.
TYPICAL APPLICATIONS
Small robust design and high accuracy of the Kestrel Pocket Anemometer makes it an
extremely versatile air flow measuring instrument, ideal for numerous applications:-
Agriculture - checking conditions
for crop spraying or burning.
Aviation - ballooning, gliders, hang
gliders, micro lights, parachutists, paragliders, sky diving.
Civil Engineering - site safety,
working conditions, safe operation of cranes, wind stress measurements.
Coast Guard - assessing conditions
for survival or safety.
Education - air flow measurements
and experiments, assessing outdoor conditions for school sports, environmental studies.
Fire Fighters - indication of fire
spreading hazard.
Heating and Ventilation - air flow
measurements, checking the condition of filters.
Hobbyists - Model aircraft, model
boats, kite flying.
Industry - air flow measurements,
pollution control.
Police - measurement of cross winds
on roads.
Outdoor activities - archery,
cycling, fishing, golf, sailing, shooting, track and field sports.
Outdoor workers - assessing
conditions.
Science - aerodynamics,
environmental science, meteorology.

The Beaufort Wind Scale
The Beaufort Scale, used throughout the marine world, has developed over
many years since it was first devised by
Admiral Francis Beaufort in 1806.
Today, the Beaufort scale is defined for seamen in terms of sea state.
It's emphasis is more on the observed effect of the wind, rather than the
actual wind speed.
