 Kestrel 4000NV Wind & Weather Meter
The Kestrel® Tracker is the next generation of weather monitoring. You can now measure EVERY major environmental condition, easily and accurately, right in the palm of your hand. The chart mode allows users to recall and graph up to 2000 measurements, along with the date and time of storage. Barometric Pressure, Altitude, Density Altitude, Temperature, Humidity, Wind Speed, Wind Chill, Dew Point, Wet Bulb, and Heat Index... all in one pocket sized instrument.
Due to overwhelming demand from our military customers. These models have the same features as their more colorful counterparts, but are olive drab with a visible red backlight, which helps sustain the user's natural night vision. Military personnel and pilots flying in darkness are often concerned with preserving their night vision.
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. The units' red backlight is also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations.
