The sensor is made of a thermopile transducer and it can be classified as First Class or Second Class, according
to ISO9060 and to standard classification for pyranometers, which defines specific performance and
construction features, ensuring high accuracy and sensibility. The transducer is protected by a quartz glass
dome (K5), which ensures high sensibility in 0.3µm 3µm spectrum. The sensor is made according to WMO
standards (World Meteorological Organization).
