Toroidal Conductivity
Input Voltage to Coil
Drive Coil
Sample
Induced Current dependent
on the Conductivity of the
Sample
Pick-up Coil
Sample
Electric current is induced to flow through solution by voltages applied to Drive Coil
If solution path lies entirely within toroids (as in flow-through applications), this
circuit path must be completed through conductive metal parts external to the
solution path - “grounding strap”, contact rings, etc.
