The compacts are predestined for use in building technology systems, in industrial power plants, wind power plants, and in environmental protection everywhere where precise weather data must be determined and converted for control technology purposes. The different electrical outputs are universally compatible, also with other innovative systems. Selected and tested materials ensure the operation even under extreme conditions. The housings are made of seawater-resistant anodized aluminum. Cupstar and wind vane are made of glass fiber reinforced special plastic and thus extremely durable and resistant.
