Kestrel 4000 Weather Meter

Kestrel 4000 Weather Meter

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 series is now available with Bluetooth Technology, which allows you to communicate with your Kestrel at a range of up to 30-feet, and maximize the battery life of your weather meter. 

Each Bluetooth Meter includes custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data and transfer data to other applications. It is no longer necessary to purchase an interface separately, the new Kestrel Meters with Bluetooth include the software necessary to communicate wirelessly. 

For military professionals, the Olive Drab NV version of the Kestrel 4000 features a night-vision preserving backlight. 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, so is not compatible with night-vision equipment.)

The advantage the Kestrel 4000 provides to scientists, athletes, firefighters, automotive technicians, and agricultural specialists is immeasurable. With Kestrel 4000 technology, you will not only know the current weather conditions, but be able to track changes in the environment and therefore make predictions as to what may happen next. 

Included with the Kestrel Meter 4000 is: Soft Carry Pouch, Wrist & Neck Lanyard, 5 Year Warranty, 2 AAA Batteries, Kestrel Certificate of Conformity
