Kestrel 3000 Wind Meter
Velocity,Temperature, Humidity, Wind Chill, Dew Point
DESCRIPTION
The Kestrel 3000 is a unique hand-held instrument for measuring wind speed, temperature, wind chill, relative humidity, heat stress index and dew point temperature. Pocket-sized and easy-to-use, it allows you to take fast, accurate readings of the environmental conditions whenever and wherever you are. It can track maximum and average wind speeds along with current readings, and displays wind speed in your choice of knots, meters per second, kilometers per hour, miles per hour, feet per minute and Beaufort force. Temperature, wind chill, heat index and dew point temperature can be displayed in °C or °F. Relative humidity is expressed as a percentage. Measuring modes and display units can be changed at any time and all functions are controlled with only three buttons. The large liquid crystal display is easy to read, even in low light.
The Kestrel 3000 measures wind speed with a large-diameter precision ultra-light impeller, which turns on sapphire bearings, providing excellent accuracy (± 3%), and the ability to measure the slightest breeze (0.3 M/S). The impeller and protective housing pop out without tools for easy and inexpensive replacement, ensuring that the Kestrel’s high accuracy can be maintained even if the impeller becomes damaged or worn.
For temperature readings, the Kestrel uses an external thermistor for fast response and accuracy of ± 1.0°C. The capacitive humidity sensor is factory calibrated to ± 3% accuracy. Heat index measurements are accurate to ± 3% and dew point temperature to ± 2%. Wind chill, heat stress index and dew point temperature are automatically calculated using U.S. National Weather Service formulas.
A hard slip-on case protects the Kestrel 3000 display, buttons and impeller from damage. The user-replaceable battery provides 300 hours of use. The Kestrel 3000 is covered by a full one-year warranty and is protected by US patent No. 5,753,784.
