4. RaZON
+
PR1 Pyranometer
The RaZON
+
standard pyranometer is the PR1. This pyranometer is equipped with a quartz diffusor, spherical dome and a fast detector.
It has the smart interface to communicate over RS-485, Modbus® RTU with the RaZON
+
. Because it has no integrated bubble level and
levelling feet, it is intended only to be used on the RaZON
+
. The PR1 and PH1 are almost identical (apart from dome and tube) the
communication with the PR1 is fully identical to the PH1.
