Precipitation Monitor



The instrument serves for detecting start and end of precipitation. It can be used as status indicator or as signal transmitter for the controlling of security devices against precipitation such as windows, venetian blinds, awnings.
The precipitation is acquired opto-electronically via a measuring surface of approx. 25 cm². A relays contact signalises the precipitation status (precipitation yes/no).
An integrated heating avoids possible snow-covering resp. freezing of the instrument during winter operation.
Delivery is effected completely with mast holder which can be used also for wall mounting.
