Instruments which measure wind speed
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 of wind. Units with smaller impellers simply can’t match the Kestrel’s performance at low wind speeds. If damaged, a new calibrated impeller can be purchased and popped in without tools, restoring like-new performance. This patented removable impeller technology keeps Kestrel Meters accurately measuring the wind speed for years.
