Kestrel 4000NV with Bluetooth Pocket Weather Tracker

Kestrel 4000NV Pocket Weather Tracker is the most comprehensive pocket weather meter on the market. For just under 4 ounces, you get every environmental reading with the press of a single button. The 4000NV is unparalleled in its ease of use and totally customizable navigation and data display. In addition to measuring the current conditions, it tracks and stores up to 2000 sets of data, and data can be uploaded to a PC.

Durable? You bet. The 4000NV has been subjected to impact, water submersion and extreme temperature tests, and keeps on working. Kestrel 4000NV’s have been put to the test in some of the harshest conditions on the planet. Military operations, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and IRL pit crews are just a few who rely on a Kestrel 4000 to provide them with the crucial environmental data they need.

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.

Now, with integrated Bluetooth technology, both real-time and logged data can be transferred wirelessly and automatically to a Bluetooth enabled laptop or PDA. Kestrel Pocket Weather Meters have specifically customized Bluetooth integration to answer the unique needs of our customers:

• Streamline your work and reduce your equipment in the field - wireless data transmission eliminates the need for a separate interface and cabling.
• Every Bluetooth Kestrel will include custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data, and transfer data to other applications.
• Data transmission range adjustment allows you to maximize power to communicate with your Kestrel at up to a 30 feet range, or reduce power for closer, more secure operation.
• Individual unit ID’s ensure you pair with the Kestrel you want, even when more than one system is operating in the same area.
• Permanently coded unique 4-digit Pin numbers provide extra security when pairing and transmitting data.
