About this deal

You may not without our prior written consent assign, transfer, sub-contract or otherwise deal with any of your rights and/or obligations under these terms and conditions. View your live & historical data on your mobile device - up to 100ft away from the Kestrel (requires the LiNK wireless communication option). You hereby waive all your moral rights in your content to the maximum extent permitted by applicable law; and you warrant and represent that all other moral rights in your content have been waived to the maximum extent permitted by applicable law. The Kestrel LiNK® App for iOS/Android allows you to Wirelessly connect with iOS and Android devices and remotely view real-time environmental data and receive alerts for changing conditions. Available for your Kestrel 5 Series Meter or DROP Logger, Kestrel LiNK also provides easy transfer of the Kestrel’s stored data log, a clear graph of all historical data. Alerts can be customized based on temperature, heat index, wind, or other measurements. LiNK enables easy firmware updates of Kestrel 5 series meters. Calculates relative humidity, station pressure (absolute pressure), altitude (barometric), barometric pressure, density altitude, dew point temperature, heat stress index, wind chill, wind speed and wet bulb temperature (psychometric)

Air pressure that would be present in identical conditions at MSL. Station pressure compensated for local elevation provided by reference altitude. Requires accurate reference altitude to produce maximum absolute accuracy Initially you will see that, apart from target A, they all say Active No. If you set one of these to active, you can now select it from the main screen by scrolling left or right while Tgt is highlighted. Data from weather stations with anemometers and doppler radars with wind speed measuring capabilities are used by big computer models to make weather forecasts. The invention of the anemometer has greatly improved our knowledge about weather processes.If any unlawful and/or unenforceable provision of these terms and conditions would be lawful or enforceable if part of it were deleted, that part will be deemed to be deleted, and the rest of the provision will continue in effect. F to 131° F | -10 °C to 55 °C Measurements may be taken beyond the limits of the operational temperature range of the display and batteries by maintaining the unit within the operational range and exposing it to the more extreme environment for the minimum time necessary to take reading.

All measurements of the top highest wind speeds were done using automatic systems. The reason that there are no handheld devices in the top is that human beings can only withstand wind speeds up to 160-240km/h (100-150mph). Conclusion The first wind gauge was created around 1450 A.D. by Italian author and architect Leon Battista Alberti. Over the centuries, it has been improved by a number of different people. One of the more notable improvements of the wind meter was the invention of the three-cup wind meter by John Patterson in 1926. Some of you will have noticed in the top right of your display an A. What does this mean and why is it there? The Elite 5700 AB has the ability to store information for five separate targets at the same time. This can include all of the above information for each target, allowing you to set up for and engage five different targets at different ranges, angles and locations. They can be viewed individually or as a simple range card. Our principal place of business is at The Lodge, Unit 1 Barnes Farm Business Park, Barnes Lane, Milford on Sea. SO41 0AP.This type of anemometer is used to measure wind speeds over a great area, but it is less accurate than other anemometers. The reason we don’t have data from other anemometers in tornadoes is quite obvious: they tend to get destroyed when a tornado hits! Highest Wind Speed Outside a Tornado One-button clear and restart of Max Wind Gust and Average Wind measurement by powering down and restarting unit. Perceived temperature resulting from combined effect of wind speed and temperature. Calculated based on the NWS Wind Chill Temperature (WCT) Index, revised 2001, with wind speed adjusted by a factor of 1.5 to yield equivalent results to wind speed measured at 10m above ground. Measurement range limited by extent of published tables. Logged history stored and displayed for every measured value. Manual and auto data storage. Min/Max/Avg history may be reset independently. Auto-store interval settable from 2 seconds to 12 hours*, overwrite on or off. Logs even when display off except for 2 and 5 second intervals. Kestrel 5 series units hold over 10,000 data points.

Temperature indicated by a sling psychrometer. Due to nature of the psychrometric ratio for a water-air system, this approximates the thermodynamic wet-bulb temperature. The thermodynamic wet-bulb temperature is the temperature a parcel of air would have if cooled adiabatically to saturation temperature via water evaporating into it. Paragliders and glider aeroplanes use the data from the anemometer to ensure conditions are safe to fly

When would you use an anemometer?

Polymer capacitive humidity sensor mounted in thin-walled chamber external to case for rapid, accurate response (US Patent 6,257,074). To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift +/- 2% over 24 months. Humidity sensor may be recalibrated at factory or in field using Kestrel Humidity Calibration Kit (NK PN-0802). Optional LiNK Wireless (Bluetooth Low Energy) Communication. Comes with free apps for iOS & Android, and free software for Windows & Mac, inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. Startup speed stated as lower limit, readings may be taken down to 0.4 m/s | 79 ft/min | 1.5 km/h | .9 mph | .8 kt after impeller startup. Off-axis accuracy -1% @ 5º off-axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. *F/S only in Ballistics units. Beaufort not available in Ballistics units. An anemometer is a device that is used to measure the speed of wind and is a common weather station instrument. To learn more, please see our complete guide to anemometers.
