Kestrel Weather Instruments
Kestrel® 2000
Pocket Thermo Wind Meter
-
The NK
Kestrel 2000 Thermo-Anemometer is a pocket-sized
precision instrument for measuring wind speed, temperature and
wind chill.
-
It's ready whenever you are -
just slip off the protective case and press "ON" for fast,
accurate readings of the environmental conditions that affect
you most.
-
The large liquid crystal display is clear and easy to read
under almost any conditions.
-
The Kestrel 2000 can
track maximum and average wind speeds along with current
readings, and can display wind speed in your choice of knots,
meters per second, kilometers per hour, miles per hour, feet per
minute or Beaufort scale.
-
Temperature and wind
chill can be displayed in °C or °F.
-
Measuring modes and
display units can be changed at any time and all functions are
controlled with only two buttons.
-
The Kestrel 2000
relies upon a precision ultralight impeller mounted on jewel
bearings to measure wind speed.
-
It provides
excellent accuracy (± 3%) and the ability to measure the
slightest breeze (0.3 M/S).
-
It is protected
be a reinforced fiberglass housing and can be replaced easily and
affordably should it become damaged or worn.
-
For temperature
readings, the Kestrel uses a fast-responding thermistor accurate
to +/-1 °C.
-
Wind chill is calculated
from wind and temperature data using the U.S. National Weather
Service's official tables.
-
The Kestrel 2000
is waterproof and floats and comes with a convenient
neck lanyard.
-
The battery is easy to replace and provides
400 hours of use.
-
The protective case prevents damage to the
unit.
-
Performance is guaranteed for one full year.

Temperature
Limitations
The Kestrel temperature sensor is able to measure temperatures as
low as -30C (-22F) and as high as 70C (158F). The sensor and
electronics simply won't measure beyond this range. The Kestrel is
able to display wind chill measurements lower than -30C, depending on
wind conditions. It is also able to display heat index measurements
above 70C, depending on humidity conditions. Furthermore, the Kestrel
display will not function if the display itself gets below -15C.
However, if the unit is kept in a pack or pocket or other warm area,
the display itself should not get this cold. In other words, try not
to leave the Kestrel outside in temperatures below -15C.
Full
one-year warranty on entire system, covering manufacturing defects.
