Nielsen-Kellerman, , designing, manufacturing and distributing Kestrel Weather & Environmental Meters for 15 years. NK's team of experts and engineers are determined to make the most accurate and reliable handheld weather devices available. NK continuously dedicated to researching ways to improve the Kestrel line and create new products to meet our customers' needs.
Every single Kestrel Weather & Environmental Meter 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. What does that mean for the customer? They can be absolutely sure that their weather readings are accurate to the stated specifications. Some competing weather instruments claim the same specifications as Kestrel, but only Kestrel certifies their accuracy.
For an additional charge, NK can even provide a NIST-traceable Certificate of Calibration that specifies exactly which values were measured in each multi-point calibration, and details the calibrated standard used for testing. Our 30-day satisfaction guarantee covers accuracy concerns as well. If a customer questions their unit’s accuracy after purchase, they can contact us and we’ll double-check every calibration to verify the unit meets specifications.
