A - Yes there are several accessories and replacement parts available for the Kestrel series of rotating vane anemometers International delivery is available for this product. The cost and delivery time depend on country. 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.

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.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. 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. With a simple three button operation the Kestrel 1000 wind meter offers readings in mph, km/h, ft/min, m/s, knots and Beaufort. This handheld anemometer (wind speed meter) is drop-tested to MIL-STD-810F making it extremely durable as well as being waterproof it can also float in water.

Ultra high intrascene dynamic range – 69dB – Enables simultaneous capture of bright & dark portions of a scene Ultra high intrascene dynamic range | Enables simultaneous capture of bright & dark portions of a sceneRaptor 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). Temperature that a volume of air must be cooled to at constant pressure for the water vapor present to condense into dew and form on a solid surface. Can also be considered to be the water-to-air saturation temperature.

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

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. 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 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 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.
