Kestrel Meters is a proud member of Nielsen-Kellerman family, which has been in business for more than 30 years, and has focused relentlessly on meeting the specialized measurement needs of demanding outdoor customers. Olympic athletes, firefighters, and military professionals are just some of the NK customers who rely on company’s products for accuracy and durability. Delivering anything less than the highest level of quality is not an option. Whatever the niche, NK know their customers won't forgive us for letting them down, and will tell their friends what they think of us, good or bad.

Every NK product undergoes rigorous functional and sealing testing and, where applicable, calibration against NIST-traceable standards, before it leaves the plant. Every product is also covered by a full warranty against defect or failure to perform (two to five years depending on product).

The company has been researching, 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. The company is continuously dedicated to researching ways to improve the Kestrel line and create new products to meet their customers' needs. While it may not be obvious when you look at a Kestrel side-by-side with a competitor's weather meter, there are very important differences that make Kestrel the best choice for almost every application.

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.
