In addition, the Kestrel 4500 has a built in digital compass. This allows you to track and log wind direction as well as wind speed. The wind direction is displayed in degrees and cardinal compass points. By setting a reference target or runway heading, the Kestrel 4500 will automatically calculate crosswind, headwind and tailwind when measuring the wind speed. The digital compass can also be used to display forward heading with reference to either magnetic or true north. At the touch of a button environmental conditions are clearly shown in digital or graphical form. Individual functions can be displayed in three different formats: current, minimum/maximum/average and chart. There are also three user screens, which can be customised to simultaneously display the three most appropriate functions for the application. Combined with the optional Vane Mount and Mini Tripod, the Kestrel 4500 becomes a complete weather station. This is ideal for use in remote locations for short term weather monitoring, being extremely light-weight and portable. Bluetooth® model available Ideal for streaming real-time data to laptop or PDA actual size (A4 page) For those with after dark requirements, the Kestrel 4500NV (with an olive drab case) is available with a low intensity red backlight to preserve night vision. The Kestrel 4500 can be set up to log data automatically (as well as manually) at programmable intervals, in order to display a history of weather information. Graphs display up to 2900 data points and the value, time and date of capture point can be shown. The stored data can also be uploaded to a PC, for analysis/storage with the optional Kestrel Interface and Communicator software. ® High precision Zytel bearings and a lightweight impeller provide accurate air flow measurements and the ability to operate at speeds as low as 0.6 m/s. The impeller is user-replaceable in case of damage, also ensuring high accuracy levels are maintained for life. An integral flipopen hard cover protects the impeller when not in use. The Kestrel 4500 is powered by two easily replaceable, AAA batteries and has two power saving modes to prolong battery life. All text can be displayed in one of five languages: English, French, Italian, Spanish or German. Every Kestrel 4500 is individually calibrated before it leaves the factory and comes with a free Certificate of Conformity.
