We are an Authorized NK Kestrel Dealer! Our price for this product is the lowest NK allows it’s dealers to sell it for. Anyone claiming to be a dealer who advertises this item or accepts best offers lower than our price is most likely not a Kestrel dealer. Manufactured in the USA! Many Kestrel users need to know everything that the weather is doing, but dont need to log the data. We developed the Kestrel 3500 just for them. It provides comprehensive environmental data on nine different measurements with the simplicity of the Kestrel 1000. Simply turn it on and scroll left and right to see exactly what the environment is doing. When youre done, slip on the hard cover and your Kestrel 3500 Pocket Wind Meter is just about indestructible. While the weather can dictate the comfort level of individuals working or playing outside, it plays an even bigger part in many professionals jobs. Irrigation professionals use the Kestrel 3500 to ensure they are irrigating efficiently and the water they are dispersing is actually hitting their intended target, and not evaporating or blowing away. And on construction sites Kestrel users are preventing plastic shrinkage cracks and curing concrete more effectively with their Kestrel 3500. Certified and Guaranteed Accuracy Every single Kestrel manufactured at Nielsen-Kellerman is calibrated for every single value, either directly against NIST-traceable standards or against an intermediary standard that is calibrated daily. 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. A slip-on protective cover. CR2032 coin cell battery (Average life 300 hours).
