Actinograph
Definition
A structural meteorological instrument utilized for the continuous and automatic graphical recording of the intensity of direct and diffuse solar radiation onto a special chart called an actinogram. The device operates based on a bimetallic or thermoelectric system sensitive to temperature variations induced by solar rays, transmitting the mechanical movement to a recording arm with a pen that traces the radiant values curve onto a rotating drum.
