Dieser Vier-Komponenten Strahlungsbilanzsensor von Apogee Instruments liefert individuelle Messwerte der vier Komponenten als SDI-12 Signal. dadurch werden weniger analoge Kanäle gebraucht und man erhält trotzdem alle Informationen vom Sensor. Inklusive mit dem Sensor sind ein Montagearm, Kabel zum Anschluss am Datenlogger und ein Transportkoffer.

An example program that uses the M! SDI-12 command to measure the incoming short-wave (SW) radiation, outgoing SW radiation, incoming long-wave (LW) radiation, and outgoing LW radiation of the SN500SS. The example program supports the CR6 and CR1000X data loggers.
