Kestrel 4000 Portable Weather Station with Altitude Density

4000 Kestrel

Kestrel 4000 speed; maximum/average wind, various temperature indices, humidity;, dew point, pressure, altitude and density altitude;.


The Kestrel 4000 is a true mini-computer of meteorological data. In fact, for each type of measurement is able to detect the minimum, maximum and a very detailed graph based on surveys of hours and days passed.
The essential and intuitive work menus allow you to have in the palm of your hand a real weather station, reliable and easy to use.

It reads the current, maximum and average wind speed, temperature, cooling index, relative humidity, apparent temperature, dew point, atmospheric pressure, altitude, wet bulb temperature, altitude density, time and date. The Kestrel 4000 can also be interfaced to the PC via accessory #181-4010.

Kestrel Line has been carefully designed with the highest quality standards to ensure maximum precision and durability.
All models are able to collect wind data with extreme reliability, while on the more advanced models there are countless weather features that are useful not only for owners of sailing boats, but also for those who want to go out to sea in complete safety, monitoring the weather conditions.
The wind measurement is taken by means of a precision fan with sapphire carriers that allows you to read the data with high accuracy (+/- 3%) and start measuring at a very low wind level (0.3 Ms). The fan is also made of highly shock-resistant material and can be easily replaced.
