The Kestrel 4500 is now available with integrated Bluetooth® wireless technology. Both real-time and logged data can be transferred wirelessly and automatically to a laptop. The included PC Communicator software is 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 Bluetooth equipped 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.
The Kestrel 4500 senses wind direction and wind speed utilizing its built-in digital compass. It also calculates crosswind and headwind/tailwind with reference to a user-set target heading, and stores the information along with all the other environmental readings in its 1400 data point memory.
Pair the 4500 with the (NC-10912) Kestrel Vane Mount and you have a data-logging weather station that sets up in seconds and rotates in the slightest of breezes. The whole kit is the ultimate in portability. It packs down into a 2 x 6 inch pouch and weighs under eight ounces.
