Kestrel 1000 Wind Meter

Product Information

Channel Islands; Inflatable dinghy price on request Channel Islands; Flares not available to ship at this time Perceived 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 Our in-depth knowledge and experience gives us a unique Space Heritage. Our camera cores are SWaP optimised, athermalised and ruggedised to withstand launch conditions and maintain optical performance while being exposed to the extreme operating conditions experienced in the space environment. We offer flight-ready COTS options as well as custom OEM designs. The Kestrel 1000 series rotating vane anemometer designed for measuring wind speed. The entry-level meter provides accurate current, average and maximum wind speed readings without compromising on functionality and performance. With a fully sealed IP67 electronics enclosure the robust instrument even floats if accidentally dropped in water. Constructed from impact resistant plastic and corrosion proof materials the Kestrel 1000 anemometer is ideal for any outdoor enthusiast.

Temperature that a volume of air must be cooled to at constant pressure for the water vapor present to condense into dew and form on a solid surface. Can also be considered to be the water-to-air saturation temperature. 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. While most weather meters are all built the same, some may offer different functionality. One common feature added to these devices is temperature. Some, like those used in firefighting, might also include a humidity sensor. Wrapping Upinch diameter impeller with precision axle and low-friction Zytel® bearings. Start-up 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 start-up. Off-axis accuracy -1% @ 5° off-axis; -2% @ 10° -3% @ 15°. 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). 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. CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge).

We’ve also developed a 100-point rating system that judges each handheld weather station tested on the same metrics. We judge accuracy (or performance), affordability, durability, feature set, and ease of use. These categories are weighted to emphasize accuracy and affordability — which makes up half of a handheld weather station’s score itself.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. All Kestrel models can be fitted to a portable rotating wind vane mount and tripod, to create a very portable and accurate weather station. Compact in design the Kestrel 1000 utilises high precision bearings and a lightweight rotating impeller to deliver exact airflow measurements even at lower wind speeds. Microprocessor technology automatically counts the number of revolutions per second to calculate the wind speed. Final measurements are plainly shown in 9mm high digits on the liquid crystal display. For nearly 20 years on the portable weather meter market, the Kestrel 1000 is still one of the most reliable handheld weather meters. Wind and weather meters are meant to be used outdoors, so device construction is important. If you are using the device in harsher environments, ensure it is built well, which most higher-end devices are. For those using their devices casually, durability is far less of a concern. Many of them are waterproof. Functionality

Kestrel 1000 Wireless Pocket Wind Meter with Anemometer

The operation is straightforward, with 3 easy to use buttons, data can be viewed in average, current or maximum displays. The buttons also provide a data hold function. Auto switch off the device, 45 minutes after the last key press helps to preserve battery life. One-button clear and restart of Max Wind Gust and Average Wind measurement by powering down and restarting unit. Designed and manufactured in the USA from US and imported components. Complies with Regional Value Content and Tariff Code Transformation requirements for NAFTA Preference Criterion B. Difference between dry bulb temperature and wet bulb temperature. When spraying, indicates evaporation rate and droplet lifetime. Safe range for pesticide spraying is 4 to 16 °F / 2 to 9 °C. Advanced video enhancement and signal processing features – Optimizing image quality and output in real-time. View full DetailsHermetically 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. 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).
