Kestrel Meter Replacement Impeller

For compatible Kestrel Weather Meters.

Using a built-in digital compass, the Kestrel 4500 measures wind direction in addition to wind speed and effective crosswind, headwind, and tailwind. Simply point the instrument in the direction of the wind to instantly obtain wind speed and wind direction in degrees and cardinal compass points. Readings can be stored in the 2,000 data-set memory. Combine the Kestrel 4500 with a portable vane mount and portable tripod (each sold separately) for a data-logging weather station that rotates in even the slightest breeze and is ideal for short-term monitoring. In addition to taking wind measurements, the unit also measures air, water, and snow temperature; wind chill; relative humidity; dewpoint; heat stress index; barometric pressure; altitude; density altitude; and wet bulb temperature. Measurements are shown on the backlit display. You can easily customize screens to display user-selected measurements as well as graph and recall trends. The waterproof Kestrel 4500 floats and includes a protective pouch, neck and wrist lanyards, and 2 AAA batteries. Five-year manufacturer’s warranty. Assembled in the USA.

*Humidity sensor can be recalibrated in the field. Accurate readings may be taken beyond these temperature limits by exposing the unit for the minimum time necessary to take and record measurements.
