ABSTRACT:
An instrument for measuring body resistance to ion and ionophoresis applications comprising a reading circuit for providing a reading of body resistance values after an established period during which the resistance values become stable, and a principle circuit including two transistors for initially obstructing current to a bridge and two condensors for actuating the two transistors, the condensors providing a discharge time equal to the time necessary for the body resistance values to become stable. Two relays are activated by the current circulating in the transistors and close the reading circuit.
