  • 1 B
Accuracy (+/-): Larger of 3% of reading, least significant digit or 20 ft/min
Notes: 1 inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. Startup speed stated as lower limit, readings may be taken down to 0.4 m/s | 79 ft/min | 1.5 km/h | .9 mph | .8 kt after impeller startup. Off-axis accuracy -1% @ 5º off-axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. *F/S only in Ballistics units. Beaufort not available in Ballistics units.

Ambient Temperature
Units of Measure: Fahrenheit, Celsius
Specification Range:
  • -20.0 to 158.0 °F

  • Urgent need for my K2 winter expedition.

    I needed urgent for my K2 winter expedition. I was on the last min and needed the goods to be sent in Iceland. Their chat online worked 100% and I was able to add on one extra peace even after I checkout. They send with UPS same day and I had the package 3 days later here in Iceland. Extreme Meters works and has good service I recommend them.

  • The service was prompt and cordial.

    The service was prompt and cordial. The Kestrel is used to measure wind velocity and temperature when applying pesticides for agriculture crop production. It is also used to measure weather conditions for livestock comfort.
