3500nv Pocket Weather Meter Olive Drab - Night Vision
SKU: KEST0835NV Part Number: 0835NV Barcode: 730650035014
Product Information
The Kestrel 3500 measures every environmental condition simply with the press of a button!
Note: 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.
The Kestrel 3500 Wind Meter has the most functions of any Kestrel Meter in the 3000 series. The Kestrel 3500 measures temperature, wind speeds, barometric phenomena, pressure trends of up to 3 hours, and more. The Kestrel 3500 provides a complete range of weather measurements, but does not log accumulated data like the more high-tech weather meters of the Kestrel 4000 series. For those who need a full reading of only the latest weather information, the 3500 is the ideal Kestrel Meter.
