Instrument to measure the sunshine duration and direct radiation.
The sunshine duration is defined as period, in which the direct solar radiation exceeds the threshold of >120 W/m. The sensor sends a digital Yes/ No-information for the sunshine
duration, and a voltage as information for the direct radiation. Connectable heating avoids a
possible dewing on the instrument. Delivery includes a test certificate.
