Description

The CM121B/C Shadow Ring can be used with Kipp & Zonen pyranometers, smart pyranometers, pyrgeometers and UV Radiometers to shield the instrument from direct radiation.

The combination of a global measurement instrument and CM121B/C Shadow Ring offers a simple solution to the problem of measuring diffuse radiation from the sky.

The shadow from the ring is designed to cover the pyranometer dome completely, with the ring having been designed to work without needing any adjustment for several days. Naturally the ring will also intercept a small part of the diffuse radiation from the sky and a table is provided to a aid in the correction of the ring to compensate for this.
