roentgenometer, radiometer
1. An instrument for measuring the intensity of radiation.
2. An instrument designed for measuring the mechanical effect of radiant energy.

It consists of a number of light discs, blackened on one side, placed at the ends of extended arms, supported on a pivot in an exhausted glass vessel.

When exposed to rays of light or heat, the arms rotate.
