Kestrel 3000 Weather Meter

Product Information

Once you have chosen your gun/bullet name, press the down arrow and again highlight MV. If you need to, you can obtain your MV from the box that your ammunition came in, but this will only be a very rough approximation. Ideally, you will want to use a chronograph to establish your correct MV, although we will be able to correct this later. Any disputes relating to these terms and conditions shall be subject to the exclusive jurisdiction of the courts of England.

Data is transmitted wirelessly via Bluetooth® Low Energy within wireless range (100’ line of sight– reduced by walls and obstructions). Mobile device and Kestrel must remain within range to trigger alerts. RTd is for the direction of the twist on your barrel. Most rifle twist directions are right-hand twist, but a small number of left-twist barrels do exist. Vane anemometer - These types are also known as propeller or windmill anemometers. Like cup anemometers, they use wind blades that turn, instead of cups. Some handheld propeller anemometers are also called impeller wind monitors because their propellers blades are protected by a caging unit to protect your hand. Anemometers can accurately monitor the wind speed and provide the data for the measurements in various ways. There are several types of anemometers and each one functions differently depending on what type it is and what type of wind measurement application it is used for. Most handheld wind speed monitors are rugged and durable to withstand the elements that they may be presented with, as well as being weatherproof, especially those that can be mounted to measure over long periods of time. They are used in a variety of applications from weather predictions to high-tech scientific research labs. Types of AnemometerPerceived temperature resulting from the combined effect of temperature and relative humidity. Calculated based on NWS Heat Index (HI) tables. Measurement range limited by extent of published tables 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. You hereby agree that we may assign, transfer, sub-contract or otherwise deal with our rights and/or obligations under these terms and conditions. Thanks to the patented external temperature sensor and waterproof construction, the Kestrel 2000 weather meter can take accurate water and snow temperature readings, and since it is isolated from the case, you can be sure that the temperature reading is accurate and not influenced by your hand warming the unit.

On occasion, you are going to notice that the first wind measurement is saying something like ‘.068L’, yet the wind reading is saying ‘3.76R’. You know the wind is coming from the right, so why is the Kestrel saying to aim off to the left as the lowest wind reading? The simple answer to this one is spin drift. If you have no wind to affect the bullet you will still need to hold off to the left to counter the spin drift. Your Kestrel can be set to calculate and thus compensate for spin drift. Spin drift is turned on by default. It can be turned off via the Environment menu. Ultrasonic anemometers– The professional standard anemometers measure wind speed using high-frequency sound. It has two of three pairs of sound transmitters and receivers mounted at right angles to one another. Built in electronic circuits measure the time it takes for the sound to makes its way from each transmitter to the corresponding receiver. The circuits measure the difference in speeds of the beams and use that to calculate how fast the wind is blowing. Now you need to set your latitude; this is done from the Environment screen. Scroll to Lat and set your latitude – don’t forget to change this if you visit another country or are a long way from home. This is essential for the correct function of the Coriolis effect. Use an internet search engine to find your latitude (www.gridreferencefinder.com). With Tgt (Target) highlighted, press select (using the centre button which looks like a keyboard return symbol).

Kestrel 5 Series Certificates of Comformity

The types of anemometer depend on the type of measurement application it is used for. Below are some common types: Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Display & Battery Operational Temperature Limits. For the first part of this section, I will use the Kestrel as a stand-alone ballistic solver and I will cover the use of other devices connected to the Kestrel later. This Kestrel meter does it all. The Kestrel 5500 weather meter provides the same trusted accuracy, reliability, and usability as the original Kestrel 4500. Measure every environmental condition plus wind direction, crosswind and headwind/tailwind. Use it golfing, sailing, flying, spraying, shooting and more. Drop-proof, dust-proof, waterproof and able to withstand extreme environments without damage, your Kestrel weather meter travels with you anywhere you dare to go. A range of carry pouch options makes it even easier to take your Kestrel meter with you. 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.

Once you have set an angle to anything other than zero degrees, or one for cosine, an asterix will appear next to the range on your display. This is to remind you to remove it before changing target. Kestrel LiNK for Windows and MAC provides a desktop solution for data retrieval and export as well as firmware updates. Expanded connectivity options allow you to wirelessly connect LiNK enabled Kestrel 5 Series Meters, using the optional LiNK USB Dongle , or make a wired USB connection with non-LiNK Kestrel 5 Meters using the USB Data Transfer Cable. Wind speed can be measured in multiple units. On most wind anemometers you can choose the unit of your liking. There are three categories of units: metric units, imperial units and other units. 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 An anemometer is a device that is used to measure the speed of wind and is a common weather station instrument.

It is also ideal for farming & agriculture. Kestrel 2000 Anemometer and Temperature Meter Key Features
