Calibrations, Certifications and Service
Every NK product is tested and calibrated before it leaves our factory. We guarantee that it will perform
within specifications when you receive it. Each Kestrel Meter comes with a Certificate of Conformity, with
the stated specifications for that product on the back. If you feel an NK product is not meeting specs when
you receive it, call us and we’ll make sure you are operating it correctly. If it still appears that it may be out
of spec, return it to us within 30 days of purchase and we will test and recalibrate all values at no charge.
Beyond 30 days, we offer reasonably-priced tests, calibration services and N.I.S.T. certified calibrations as
well as Kestrel Meter tune-ups.
All of our measurements are traceable to the National Institute of Standards and Technology, ensuring
the highest level of accuracy. Our primary Calibration Standards are sent for calibration in accordance
with N.I.S.T. requirements and based on a regular schedule. Only approved laboratories and N.I.S.T
themselves are used for these calibration services. Incoming and outgoing data is supplied with the
certificate of calibration.
We also offer full factory service on every product we manufacture for as long as we make the product (and
as long after as component availability permits). If we can’t repair a product, we will offer you a brand-new
replacement under our Customer Care Program (even for accidental damage and misuse). Cost of repairs
and other important information can be found on our website.
