Secondary Standard Global solar radiation sensor


Sensor for the measurement of Global Solar Radiation (pyranometer) class Secondary Standard with thermopile. Designed to measure the global component of the sunlight on the spectrum 0,3 um - 3um according to the cosine law. Conforms to WMO for environmental monitoring, it is also an ideal instrument for photovoltaic applications according to IEC-9060 and IEC-17025. Quality instrument which, thanks to the different types of electrical outputs (voltage and current) or digital RS485 with ModBus protocol, allows it to be easily interfaced with any acquisition system.
