Description
The Kestrel 4000 Pocket Weather Meter is the first in the next generation of Kestrel Meters. It has all the wind and weather monitoring functions available with the Kestrel 3500 Wind Meter, plus the distinct advantage of data storage, graphing functions, and computer interface technology. With these additional options you will be able to record changes in the weather over time, view these changes as graphs on your Kestrel 4000's display, and even upload the data to your PC or Mac with the Kestrel Interface.
- The Kestrel 4000 Pocket Weather Meter is the baseline wind and weather meter in the Kestrel 4000 series. What sets the 4000 series apart from the rest of the Kestrel family is that these high tech weather meters have the capability to store up to 2000 points of weather data, enabling you to track changes in the environment over time. This unique function opens up an entirely new realm of weather tracking capabilities for Kestrel Meter users.
- This 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.
