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. Building and construction - Essential for health and safety around cranes, scaffolding and roofing. Gusting wind is potentially hazardous

Kestrel 1000 - Raptor Photonics Kestrel 1000 - Raptor Photonics

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.International delivery is available for this product. The cost and delivery time depend on country. 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. Ultra high intrascene dynamic range– Enables simultaneous capture of bright & dark portions of a scene 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.

inch 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). 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.

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 test 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.
