Kestrel 2000 Wind Meter

Product Information

Wind Capture - Intuitive Wind Capture feature instantly measures and adjusts for real-time wind conditions Analog or digital, we cover some of the best handheld wind speed meter, anemometers and weather stations you will come across so you can gauge wind speeds and directions accurately and safely. Nowadays, many people are using digital anemometers. These are easy to use and give very accurate results. However, analog anemometers can be just as accurate if you know how to use them properly.

An anemometer is a device that measures wind speed. An anemometer is usually a small, handheld device with a spinning wheel or cups. The faster the wheel or cups spin, the higher the wind speed. Some anemometers also have cups that face sideways. The faster the wind blows, the more sideways force it puts on the anemometer’s cups or wheel. Installation Options: Handheld anemometers can be used in a variety of settings, including wind tunnels and other research facilities. They can also be installed in vehicles for real-time speed measurements. studying wind patterns – anemometers can help researchers understand how wind moves and where it travels;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. These are just some of the features that you might find on a handheld anemometer. Make sure to select one that has the features you need for your specific application. Hermetically sealed, precision thermistor mounted externally and thermally isolated (US Patent 5,939,645) for rapid response. Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. Calibration drift negligible. Thermistor may also be used to measure temperature of water or snow by submerging thermistor portion into material -- remove impeller prior to taking submerged measurements and ensure humidity sensor membrane is free of liquid water prior to taking humidity-based measurements after submersion. Rig tension/Head Stay Sag- Rig Tension and Headstay sag can be the number one cause of speed and height issues. If you are sailing in light air conditions and the rig is too tight you will not generate enough headstay sag making the jib too flat and less powerful. On the other side, if you are sailing in over powered conditions and the rig is not tight enough, the headstay will have too much sag making the jib too deep pulling the bow down when the main is eased. This causes leeward helm and more heel angle. Really focus on the leeward shroud tension and the amount the headstay is moving. In light air you want a loose rig and more sag in the headstay, in heavier air you want a tighter rig and no movement in the headstay. Adjust this according to the wind conditions.

Accuracy: Handheld anemometers are some of the most accurate speed measuring devices available. They can provide very precise readings, making them ideal for scientific or engineering applications.

Kestrel Basic (1000-3500) Instruction Manuals

The wind speed displayed is a 3 second rolling average. This allows the unit to provide a value that is more representative of the typical, ambient conditions rather than peak speeds for instantaneous blasts of air. Convenient and reliable, the Kestrel 1000 is the perfect tool for model plane pilots, kite boarders, and other outdoor enthusiasts who rely on accurate wind speed information. The Kestrel 1000 is the most common handheld wind instrument for a DZSO (Drop Zone Safety Officer). A hard slide-on protective case, lanyard, and lithium battery are included. User Replaceable Impeller 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. These are just some examples. There are many more reasons to use anemometers! Benefits of Handheld Anemometers Price is always a consideration, but don’t forget to balance that against the other factors mentioned here. You don’t want to buy an anemometer that is inaccurate or difficult to use just because it is the cheapest option.
