Temperature and wind chill can be displayed in °C or °F.

Capable of measuring the slightest breeze, the unit uses an ultralight impeller mounted on jewel bearings to measure wind speed and provide an accuracy of ±3%. For temperature readings, the Kestrel uses a fast-responding, hermetically sealed thermistor accurate to ±1°F (±1°C). Wind chill factor is calculated automatically from wind and temperature data using the U.S. National Weather Service’s official tables.

Measuring modes and display units can be changed at any time. Results are displayed on a large, easy-to-read LCD which automatically shuts off 45 minutes after the last keypress. The Kestrel 2000 is housed in a reinforced fibreglass case that is waterproof and floats.

A convenient neck lanyard and one CR2032 battery are included. Two-year manufacturers warranty.
