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.
