The Kestrel 1000 is our most basic meter. If all you need is wind measurements, this our least expensive meter. Every meter we sell has the wind features of the Kestrel 1000. The hard slide-on case makes it durable to throw in your gear bag with no worries. 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).

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 tablesWe’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. Channel Islands; Inflatable dinghy price on request Channel Islands; Flares not available to ship at this time 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. Every Kestrel Meter features a large, 1” impeller mounted on a sapphire jewel bearing, which means it starts rotating with the slightest puff of air. For superior accuracy, the impeller housing can rotate in the unit. The patented impeller is user-replaceable by simply pushing it out with your thumbs, which means it can easily be replaced if it is damaged or worn. The measurements from the wind impeller are taken magnetically. The impeller is not glued or attached to the unit. Because every new impeller is calibrated in the wind tunnel at the USA factory, if your application demands regular calibration, simply pop in a new impeller and the Kestrel Wind Meter is restored to like-new factory calibration standards. A less accurate wind meter will only compound that error. We always recommend considering accuracy first before price, even if you’re looking for a budget model. Durability

CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge). 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. 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. 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. However, a candidate for the Best Handheld Weather Station of 2022 can’t only be a great value: it must have accurate measurements, be user-friendly, and have excellent build quality. Our review staff has years of experience using handheld weather stations and instruments: some of us are degreed meteorologists and scientists. Our writers independently research each device: we do not recommend a device simply because a manufacturer sends it to us. Our Handheld Weather Station Test ResultsAll Kestrel models can be fitted to a portable rotating wind vane mount and tripod, to create a very portable and accurate weather station.

Requires optional PC interface (USB or RS-232) or Bluetooth data transfer option and provided software. 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. 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. Advanced video enhancement and signal processing features – Optimizing image quality and output in real-time. View full DetailsWhile 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 Up 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. Height above Mean Sea Level ("MSL"). Temperature compensated pressure (barometric) altimeter requires accurate reference barometric pressure to produce maximum absolute accuracy. Both accuracy specs corresponds to a reference pressure anywhere from 850 to 1100 mBar. Top 10 Lists Our Top 10 lists count down the warmest, wettest, and snowiest places around, and explain what drives the weather in these locales. The Kestrel 1000 wind meter can easily be switched between mph, km/h, ft/min, m/s, knots and Beaufort Scale.
