Kestrel 2000 Wind Meter
Portable Air Velocity/Wind Speed and Temperature
DESCRIPTION
The Kestrel 2000 Thermo-Anemometer is a pocket-sized precision instrument for measuring wind speed, temperature and wind chill.
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 three 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 (0.4 M/S).
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.

Temperature Limitations
The Kestrel temperature sensor is able to measure temperatures as low as -30°C (-22°F) and as high as 70°C (158°F). The sensor and electronics simply won't measure beyond this range. The Kestrel is able to display wind chill measurements lower than -30°C, depending on wind conditions. It is also able to display heat index measurements above 70°C, depending on humidity conditions. Furthermore, the Kestrel display will not function if the display itself gets below -15°C. 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 -15°C.
Full two-year warranty on entire system, covering manufacturing defects.
