Description
Eppley Laboratory 8-48 Black and White Radiometer The Diffuse Pyranometer
From the manufacturer:
The Black & White Pyranometer, Model 8-48 is most often used in the highest quality networks as a Diffuse (shaded) instrument. While "all black" pyranometers such as the SPP, GPP (and PSP) are preferred for Global, Reflected or TPA measurements due to their better cosine response and time response, these do not significantly matter to a shaded pyranometer and the as Black & White has no offset that naturally occur in the all-black pyranometers, it makes it more suitable for Diffuse measurements.
