The Kestrel 3500 Night Vision Weather Meter is designed as a full weather meter that has the ability to measure environmental variables such as temperature, wind speeds, barometric phenomena, pressure trends of up to 3 hours, and more. This rugged and affordable meter provides a complete range of reliable weather measurements. For night-time use the Kestrel 3500NV features a night-vision preserving backlight which helps in sustaining natural light. The backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. (Note: This backlight appears soft greyish pink, not "red", and is still in the visible spectrum which makes it not compatible with night-vision equipment.) It has an external temperature sensor with a waterproof casing that allows you to gauge the temperature of water, snow, and the open air. The highly sensitive and user-replaceable impeller technology provides accurate wind speed info. A hard slide-on case, lanyard, and battery are also included.
