Kestrel® 1000 Pocket Wind Meter

Kestrel® 1000 Pocket Wind Meter

Overview

Here's the one that started it all! We developed the Kestrel 1000 Pocket Wind Meter in 1995 when NK co-owner, Richard Kellerman, needed a reliable wind meter for flying his glider. Over 10 years later, it looks a little slicker, and it still gives you the reliable, accurate wind measurements that you need.
Every Kestrel Meter features a large, 1” impeller mounted on a sapphire jewel bearing, which means it starts rotating with the slightest puff of air – 0.3 mph to be exact! And this unique impeller is user-replaceable, too, which means it can easily be replaced if it is damaged or worn.
If your application demands regular calibration, simply pop in a new impeller and the Kestrel Wind Meter is restored to like-new factory calibration standards. The Kestrel 1000 can easily be switched between mph, km/h, ft/min, m/s, knots and Beaufort.

1 inch diameter impeller with precision axle and sapphire bearings. Off-axis accuracy -1% @ 5º off-axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH / 7 m/s. Sustained operation above 60 MPH / 27 m/s will wear impeller rapidly and may cause destruction of impeller. Replacement impeller (NK PN-0801) may be field-installed without tools (US Patent 5,783,753).

Max/Avg Wind Speed

One-button clear and restart of Max Wind Gust and Average Wind measurement.

Display

Reflective 3 1/2 digit LCD. Digit height 0.36 in / 9 mm.

Display Update

1 second.

Display Backlight

Aviation green electroluminescent backlight.

Operational Temperature Range (LCD and Batteries)

The operational temperature range of the liquid crystal display and batteries is 14° F to 131° F / -10 °C to 55 °C. Beyond the limits of the operational temperature range, the unit must be maintained within range and exposed for minimum time necessary to take reading.

Storage Temperature

-22 °F to 140 °F / -30 °C to 60 °C.

Auto Shutdown

After 45 minutes of no key presses.

Certifications

CE certified. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge).

Batteries

CR2032, one, included. Average life, 300 hours of use, +/-depending on backlight use.

Environmental

Kestrel Meters are designed and manufactured at NK’s facility in Boothwyn, Pennsylvania, and are individually calibrated at the time of manufacture. Every Kestrel Meter comes with a Certificate of Conformity to document the unit’s accuracy—all Kestrel measurements are traceable to the National Institute of Standards and Technology, ensuring the highest level of reliability. NIST Calibration and Certification services are available.
