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.
