Kestrel Replacement Impeller

Each Kestrel impeller is individually calibrated in Kestrel’s NIST traceable wind tunnel to Kestrel specifications and comes with its own Certificate of Conformity. Simply replacing the impeller in any Kestrel meter of any age restores factory calibration.

The impeller is user replaceable, requires no tools, simply press the new impeller into place, popping out the old one at the same time.

The assembly is supplied with a retaining o-ring.
