How It Works

Conductance is the reciprocal of resistance. In this case, the Wireless Conductivity Sensor determines the conductance of an aqueous solution by measuring the current flowing through the circuit created when a voltage is
applied to a 2-cell electrode submerged in the solution. The electrode cell is constructed from insulating material with embedded with pieces of platinum that are placed at a fixed distance apart to serve as sensing elements. Because
conductivity is dependent on temperature, the Wireless Conductivity Sensor includes a built-in temperature compensation.
