SHR02 is a practical metal shadow ring that helps making diffuse solar irradiance measurements with pyranometers. The shadow ring, also known as a shadow band, prevents direct radiation from reaching the pyranometer. The combination of a shadow ring and a pyranometer is called a diffusometer by the ISO 9060:2018 standard. The compact SHR02, combined with a Hukseflux pyranometer, has several advantages over competing models. SHR02 is compatible with most Hukseflux pyranometers. Hukseflux pyranometers have very low zero offsets, so that the diffuse radiation measurement has a better uncertainty than that of competing pyranometer-shadow ring diffusometers. To avoid problems with dew and frost deposition, the user should consider using the heated SR25 or the heated and ventilated SR30 pyranometer. Using SHR02 has several advantages: - relatively small size / light weight - low-investment alternative for a sun tracker with shading-disc - high accuracy when used with Hukseflux (low zero-offset) pyranometers - save costs on expensive external ventilation; compatible with SR30 with internal ventilation Compatible pyranometers are SR15 series and SR30-D1. With the optional mounting adapter also models SR20, SR20-D2, SR22 and SR25 can be combined with SHR02 to form a diffusometer. A pyranometer is not included in SHR02 delivery. Suggested use - meteorological observations - building energy performance - solar energy studies
