Smart Pyranometer SMP11 has a dual-dome construction of higher quality glass and increased thermal mass. It uses a more sophisticated detector design than the SMP3 and is a significant step up in performance. SMP11 comfortably exceeds the requirements for ISO Secondary Standard pyranometers and is the ideal choice for site prospecting, technology research and high quality solar radiation monitoring in solar energy applications. It is also particularly suitable for upgrading meteorological networks and for use in sun tracker based solar monitoring stations.
To achieve the required spectral and directional characteristics SMP11 smart pyranometer uses thermopile detectors and glass domes. It has a built-in bubble level and adjustable levelling feet. Snap-on sun shields reduce solar heating of the housings. The waterproof connector has gold-plated contacts and is fitted with 10m of high quality signal cable as standard.
