Advanced video enhancement and signal processing features – Optimizing image quality and output in real-time. View full Details 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. 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. The Kestrel 1000 wind meter can easily be switched between mph, km/h, ft/min, m/s, knots and Beaufort Scale. 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.

Kestrel 1000 Pocket Anemometer | Force 4 Chandlery

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. 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).

Kestrel 1000 Pocket Wind Meter | Tempcon Instrumentation

All Kestrel models can be fitted to a portable rotating wind vane mount and tripod, to create a very portable and accurate weather station. 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). 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. 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 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. FunctionalityThe 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. 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

Kestrel KESTREL 1000 Rotary Vane Anemometer, 40m/s Max

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. Air pressure that would be present in identical conditions at MSL. Station pressure compensated for local elevation provided by reference altitude. Requires accurate reference altitude to produce maximum absolute accuracy CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge).

Kestrel Meter 1000 Wind Meter

For nearly 20 years on the portable weather meter market, the Kestrel 1000 is still one of the most reliable handheld weather meters. Channel Islands; Inflatable dinghy price on request Channel Islands; Flares not available to ship at this time 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.
