Handheld Weather Stations and Anemometers for 2023 Best Handheld Weather Stations and Anemometers for 2023

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. 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

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. If you’re considering a Kestrel weather meter, we’d strongly recommend models with LiNK connectivity. The free Kestrel LiNK app gives you full access to advanced tools, including shareable reports, custom display options, threshold alerts, snapshot capture, and data visualization. The app is available for both Android and iOS operating systems. Frequently Asked Questions How To Want to learn how to install your weather station? Program your weather radio? Our How-Tos section has those answers and more. All Kestrel models can be fitted to a portable rotating wind vane mount and tripod, to create a very portable and accurate weather station. 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.

Kestrel 1000 - Raptor Photonics Kestrel 1000 - Raptor Photonics

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. One-button clear and restart of Max Wind Gust and Average Wind measurement by powering down and restarting unit. 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.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). Firmware features including 3-point NUC, ALPD functionality, image flip, crosshair, edge and contrast enhancement 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. 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. CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge).
