Abstract
An instrument designed to indicate, record, and integrate radiant energy sensed by an Eppley thermopile is described. The output of the thermopile is amplified by a d-c. operational amplifier. The amplified output is connected to a meter or a recorder and totalized by an integrator. The output is calibrated in Ly min−1 and the sensitivity in the three recording modes is better than 0.02 Ly min−1.
