Temperature (3 point) @ £ inc VAT

Every single Kestrel manufactured at NK is calibrated for every single value, either directly against NIST-traceable standards or against an intermediary standard calibrated daily. (The National Institute of Standards and Technologies is the federal technology agency that works with industry to develop and apply technology, measurements, and standards.)

Every unit is shipped with a FREE Certificate of Conformity that states what calibrations were performed, and the certified performance specifications.

However, for users who must ensure their Kestrel is operating within specification, we offer a third-party calibration service.
