EST-37 PRECISION PROJECTION ELECTROSCOPE

This well-crafted electroscope is highly recommended for classroom teaching, for projecting measurements onto a screen, hence allowing an easy visualization in large groups..

Its cylindrical metal case has two parallel plane glass windows, both of which are removable, and through which one can shine a light for projection.

Close fittings and quality materials insulate the leaf system so it stays charged for several days in dry weather.

The case is mounted on a heavy metal base.

A metal cap is provided for shielding the projecting rod and knob.

The precision projection electroscope comes complete with instructions and experiments for use in projection or for direct viewing.
