Kestrel 4500 Pocket Weather Tracker

Kestrel 4500 Pocket Weather Tracker

Parameters Measured

Heading (true & magnetic), wind direction, crosswind, headwind/tailwind, Current wind speed, average wind speed, maximum wind gust, temperature, wind chill, relative humidity, heat stress index, dewpoint temperature, barometric pressure, altitude, wet bulb temperature, density altitude.

For years our customers have been asking for wind direction along with wind speed. The Kestrel 4500 Pocket Weather Tracker does just that with its built in digital compass. But it doesn’t stop there.

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.

Pair the 4500 Wind Meter with the Kestrel 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.

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 Kestrel NV line was added in 2005.

The Kestrel 4500NV 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.

Every Kestrel is individually calibrated to NIST-traceable standards and comes with a free Certificate of Conformity (Individual NIST certificates and recalibration are also available).

If your application demands regular calibration, simply pop in a new impeller and the Kestrel air velocity meter is restored to like-new factory calibration standards.
