DESCRIPTION
Exhibit 364 is an image recorder without a lens used to measure weak currents in galvanometers in which a light beam is deflected by the presence of current. It consists of two metal boxes on a wood base, one containing a wind-up spring energy source and the other the bobbins for fresh and exposed film and the film traction mechanism. Beside the handle for winding the spring, the first box has an external control of the unwinding speed and thus the linear exposure rate, for example, in cm per second. It was used in particular with the Wulf elettrometer (Exhibit 464)ISCRIZIONI
