Handheld Anemometers & Weather Stations

Trusted for research and commercial use all over the world

Kestrel weather instruments are superior-quality and made in the USA. They are trusted for research and commercial use all over the world to accurately and reliably measure wind speed, temperature, and more.

Sometimes it may not be obvious when you look at a Kestrel side-by-side with a competitor's, but there are very important differences that make Kestrel the best choice for almost every application:

Certified and Guaranteed Accuracy
Every single Kestrel is calibrated for every single value. Every unit is shipped with a FREE Certificate of Conformity that states what calibrations were performed, and the certified performance specifications. So you can be sure that your readings are accurate to the stated specifications. Some competing brands claim the same specifications as Kestrel, but only Kestrel certifies their accuracy.

Waterproof, Dustproof and Dropproof
Every Kestrel is sealed to IP-67; this means they are totally protected from dust and can be submerged in water to 1m (3ft) for up to 30 minutes without any leakage. To ensure that each Kestrel meets this standard, each one is subjected to a vacuum leak test after final assembly. Kestrel meters used in underground coal mines is testimony to their dust-resistance. The Kestrel range have been drop-tested to MIL-STD-810F United States Military Standard.

Patented Removable Impeller
The Kestrel impeller measures 1 inch across and is mounted on a nylon bearing. Its large size ensures accurate readings even if pointed off-angle from the wind, and its very low start-up speed allows measurement of the lightest puffs. Units with smaller impellers simply can’t match the Kestrel’s performance at low wind speeds. If damaged, a new calibrated impeller can be popped in without tools, restoring like-new performance.
