Description: A platinum tipped contactor makes contact with a
mercury-filled cup, regulated through a solenoid circuit. The
rate can be set at 5, 10, 20, 25, 50, 100, or 250 cps. The
apparatus can be calibrated by a micrometric screw that can be
easily removed for cleaning. (Expanded caption Copyright 1998,
