Silva Alba Windwatch Theunique hand-held weather station SILVA ALBA WINDWATCH®, madein Switzerland, is a multi-functional instrument which is designedfor outdoor people including; trekkers, paragliders, skiers, golfers,sailors, airfield ground crews, balloonists, hang-gliders, windsurfers,fire-brigades and military units. It is an essential instrumentfor field studies, crop spraying, engineers, crane operators, skyscraperwindow-cleaners, hobby meteorologists and many others.
Measures precisely: - Altitude (meters and feet)
- Barometric Pressure (hPa and inHg)
- Temperature (°C and °F)
- Wind Chill (°C and °F)
- Wind Speed (m/s, knots, km/h, mph and beaufort)
- Time (hours and minutes)
Two precision sensors/transducers: The patented highly sensitive impeller gives; Current, Peakand Average of The Peak wind speed, and Average wind speedover a selected period. While not in use the wind sensor impelleris fully protected by a simple twist of the casing - a uniquefeature!
Wind chill: Ambient temperature taking averageor peak wind speed into account The instrument floats! Unique Automatic-Software Correction in order to give correctwind speed values, i.e. software correction for the fact that wind-energyis lost, but corrected for at low wind speed and that impellershave "improved" dynamics at high wind speeds. This Automatic-software Correction means that you can rely onthe information on the display also at very extreme wind speeds!  |  |  |  | -ALTITUDE(m or ft)
