The unique hand-held weather station SILVA ALBA WINDWATCH, made in Switzerland, is a multi-functional instrument which is designed for outdoor people including:
Trekkers, Paragliders, Skiers, Golfers, Sailors, Airfield ground crews, Balloonists, Hang-gliders, Windsurfers, Fire-brigades and Military units.
It is an essential instrument for field studies, crop spraying, engineers, crane operators, skyscraper window-cleaners, hobby meteorologists and many others. Two precision sensors/transducers:
The patented highly sensitive pressure sensor fitted in the patented battery cover gives; current Barometric pressure (QNH=reduced barometric pressure at sea level), Barometric pressure over the last 16 hours (trend) and information about current Altitude | The patented highly sensitive impeller gives; Current, Peak and Average of The Peak wind speed, and Average wind speed over a selected period. While not in use the wind sensor impeller is fully protected by a simple twist of the casing - a unique feature!
