MicroVision uses a toroidal probe for conductivity measurement. The measurement is made by passing an AC current through a toroidal drive coil, which induces a current in the electrolyte solution (see diagram). This induced current in turn, induces a current in a second toroidal coil, called the pick-up toroid. The amount of current induced in the pick-up toroid is proportional to the solution conductivity.
