Kestrel 1000 Wind Meter

Product Information

Requires optional PC interface (USB or RS-232) or Bluetooth data transfer option and provided software. Ultra high intrascene dynamic range – 69dB – Enables simultaneous capture of bright & dark portions of a scene Image Credit: Kestrel The Kestrel 1000 might only measure wind, but we feel it’s a much better option (and more accurate) than the BTMeter BT-100. Which handheld weather station is the most durable?

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. DurabilityThe 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. Raptor cameras are on LEO satellites revolving at an altitude between 160 to 2,000 kilometers flying at approximately 17,000 mph. Some of our cameras have been operational for over 24 months. We offer LEO camera solutions from UV (180nm) to SWIR (1700nm). If accuracy is a concern for you, we don’t think a budget wind meter will serve you well. The Kestrel 1000 is more expensive than most other wind meters we’ve seen, but we think the added cost is worth it. Overall, we’re very impressed with Kestrel’s lineup, and it’s the reason why you’ll see their devices quite a bit in this list.

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 Results 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. 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.CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge). The operational temperature range of the liquid crystal display and batteries is 14° F to 131° F / -10 °C to 55 °C. Measurements beyond the operational range can be taken by briefly exposing unit to extreme conditions such that the display and batteries remain within the operational range. Storage range -22 °F to 140 °F / -30 °C to 60 °C. 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). 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. 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 Up

Extremely low dark current – Deep cooled to -90°C with air and liquid or -80°C with air only to enable long exposure times All measurements except those based on relative humidity respond accurately within 1 second. Relative humidity and all measurements which include RH in their calculation may require as long as 1 minute to fully equilibrate to a large change in the measurement environment. Display updates every 1 second. For nearly 20 years on the portable weather meter market, the Kestrel 1000 is still one of the most reliable handheld weather meters.The Kestrel 1000 wind meter can easily be switched between mph, km/h, ft/min, m/s, knots and Beaufort Scale. 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. Firmware features including 3-point NUC, ALPD functionality, image flip, crosshair, edge and contrast enhancement 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 handheld wind speed meter (anemometer) is a simple, reliable and extremely accurate air velocity measurement device delivering current, average and maximum wind speed readings, you can easily change between mph, km/h, ft/min, m/s, knots and Beaufort. This is the meter of choice for crane operators and water sports enthusiasts alike.

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 Building and construction - Essential for health and safety around cranes, scaffolding and roofing. Gusting wind is potentially hazardous Other options, like the Ambient Weather WM-5 and Kestrel 3500 series meters are a great mix of affordability and functionality. A - Yes there are several accessories and replacement parts available for the Kestrel series of rotating vane anemometers We have experience with all the products and companies we recommend here on TWSE. Our review staff includes degreed meteorologists and scientists, some of whom have owned the products they review for several years. Our staff has reviewed home weather gadgets for over a decade both on TWSE and elsewhere. How we testHermetically 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. 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.
