NK was the first to provide accurate relative humidity measurements from a hand-held weather meter, and the Kestrel 3000 features two patents on its humidity measuring sensors.

From the Kestrel 3000’s accurate relative humidity readings, it also calculates the dewpoint and heat stress index —important information to know when working or playing outdoors in hot and humid conditions.

A common accessory for fire departments is the field calibration kit.

The Kestrel 3000 has traditionally been the choice for firefighters.

The new Kestrel 5 Series platform adds many new features and options. If you’re familiar with the Kestrel 4500, the first thing you’ll notice is the larger, higher-resolution and contrast display and improved font readability. The Kestrel 5 series also includes a built-in dual color backlight, extra-strong polycarbonate lens and AA battery operation. Like all Kestrel meters, the Kestrel 5500 is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage – so it can so it can work or play as hard as you do, wherever you go. A range of carry pouch options makes it even easier to take your Kestrel meter with you.

The true versatility of the Kestrel 5500 becomes apparent with the addition of the Kestrel Vane Mount. This precision-engineered accessory securely mounts the Kestrel 5500 to any tripod or other ¼-20 fitted bracket. Once mounted, the Kestrel 5500 becomes a full-featured weather station – with a large wind vane and precision pivot keeping the Kestrel oriented into the wind for continuous measurement and logging of wind speed, wind direction, and all other key weather parameters. The ENTIRE Kestrel 5500 + Vane Mount kit weighs just 10.5 ounces / 295 grams, and packs into the included padded belt carry pouch that is just 2.5 x 3 x 8.5 inches / 6.5 x 7.5 x 22 cm. Providing hundreds of hours of accurate measurements, the Kestrel 5500 is truly the world’s most compact weather station, available for purchase separately.

Kestrels have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and auto pit crews are just a few who rely on a Kestrel to provide them with the crucial environmental data they need. Watch any on-screen meteorologist during a hurricane, and you’re sure to spot a Kestrel in action. Be your own meteorologist, anywhere in the world, with a Kestrel 5500.

NOTE: Range up to 100’ line of sight – reduced by walls and obstructions

In addition to measuring the current environmental conditions, the Kestrel 5500 tracks and logs over 10,000 sets of time-stamped data. Your data log can be transferred to a mobile device wirelessly with the LiNK wireless communication option and Kestrel LiNK app, or to a PC/MAC with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (available separately).

Impeller:

Every Kestrel Meter features a large, 1” impeller mounted on a sapphire jewel bearing, which means it starts rotating with the slightest puff of air – 0.48 km/h to be exact! This patented impeller is user-replaceable by simply pushing it out with your thumbs, which means it can easily be replaced if it is damaged or worn. The measurements from the wind impeller are taken magnetically. The impeller is not glued or attached to the unit. Because every new impeller is calibrated in the wind tunnel at the USA factory, if your application demands regular calibration, simply pop in a new impeller and the Kestrel Wind Meter is restored to like-new factory calibration standards. The Kestrel 1000 can easily be switched between mph, km/h, ft/min, m/s, knots and Beaufort.

For nearly 20 years on the portable weather meter market, the Kestrel 1000 is still one of the most reliable handheld weather meters.
