Having a replacement impeller ensures your Kestrel is always prepared to deliver precise wind or airflow readings.
Each impeller is individually calibrated to Kestrel standards in their NIST traceable wind tunnel and is accompanied by a Certificate of Conformity.
Simply swapping out the impeller in any Kestrel meter, regardless of its age, restores the factory calibration.
What's great? Replacing the impeller is easy and doesn't require any tools – just press the new impeller in place, and the old one pops out simultaneously, a patented Kestrel feature.
Field impeller replacement is simple, making it effortless to maintain Kestrel accuracy.
