The ion transmitter cassette is activated by the negative electrostatic radiation, whereby the negative mercury ions emit their ion radiation.

Negative cell

  1. Connection to printer 1 megohm.

  2. Anode, gold filling.

  3. Cathode with inlet and contact tip.

  4. Lid and cover of insulation material.

  5. Tooth filling of amalgam.

  6. Attachment with screw of insulation material.

  7. Zinc cylinder.

  8. Electrolyte, water -37° C.

The diagram is a general version which can vary within wide limits. The principle is based on the fact that the negative repulsion charge is greater than the mercury’s inherent ion charge. This relationship brakes the emission of ions with the result that the ion voltage of the amalgam surface will lie over the combined ion and galvanic voltage. In this situation the cell functions as an ion separator. If the negative repulsion charge in the cell is removed the ion charge diminishes, with the result that the ion voltage and galvanic voltage are combined and the programmed measurement curve disappears.

The negative radiation from the zinc cylinder has a double function in that both the activation of the mercury amalgam and the diode function take place simultaneously.
