Skywatch Wind - Wind and Tempature Meter

JDC Skywatch - Wind A pioneer in the field of hand-held anemometers, JDC Electronic has been focusing its know-how on the development of quality anemometers since 1984 with its Skywatch brand, bringing together two watchwords: simplicity & efficiency. The Skywatch Wind measures wind speed, air temperature and wind-chill rapidly and accurately. Small enough to bring anywhere, insensitive to dust and shock with a user-replaceable propeller, the newest member of the JDC family is designed and manufactured in Switzerland.
