For years our customers have been asking for wind direction along with wind speed. Recently released, the Kestrel 4500 does just that with its built in digital compass. But it doesn't stop there. The Kestrel 4500 Weather Meter also calculates crosswind, headwind & tailwind with reference to a user-set target heading. The Kestrel 4500 stores the information along with all the other environmental readings in its 1400 data point memory.

Pair the Kestrel 4500 Wind Meter with the Kestrel Meter Vane Mount and you have a data-logging weather station that sets up in seconds and rotates in the slightest of breezes. Did we mention that the whole kit is the ultimate in portability? It packs down into a 2 x 6 inch pouch and weighs under 8 ounces.

New! This Kestrel Includes Bluetooth Wireless Technology!
Kestrel's reputation for accuracy and reliability has been earned over thirteen years of proven performance in extreme environments. In many instances, the key environmental measurements from a Kestrel instrument are input into other systems ballistics calculators, fire behavior models, hazmat plume predictors, heat stress models, weather reports, research data sets and more. Now, both real-time and logged data can be transferred wirelessly and automatically to a laptop or PDA, making a Kestrel 4000 series weather meter the perfect tool for virtually any job that requires quick and truly accurate environmental data.
 

Data transmission range adjustment allows you to maximize power to communicate with your Kestrel at up to a 30 feet range, or reduce power for closer, more secure operation. Individual unit IDs ensure you pair with the Kestrel you want, even when more than one system is operating in the same area.

It also calculates crosswind and headwind/tailwind with reference to a user-set target heading, and stores the information along with all the other environmental readings in its 1400 data point memory.

Available in the NV Configuration

Military personnel and pilots flying in darkness are often concerned with preserving their night vision. Due to overwhelming demand from our military customers, the Kesrel NV line was added in 2005.

The Kestrel 4000NV is available with an Olive Drab case or a Desert Tan case. The unit has a night-vision preserving backlight which helps users to sustain natural night vision. The NV's backlight incorporates an optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. Additionally, NV backlights are also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations. This backlight appears soft greyish pink, not red, and is still in the visible spectrum, so is not compatible with night-vision equipment.

It takes 30 to 45 minutes for the average eye to adapt to darkness and maximize night vision. Even a short burst of white, yellow, green or blue light bleaches out the rod cell photoreceptors in the eye and causes night blindness until the entire adaptation process can take place again. Light in the red spectrum does not cause this bleaching out, preventing night blindness and night vision fatigue. Manufactured in the USA!

Made in the USA
