The Wireless Conductivity Sensor

The Wireless Conductivity Sensor measures the electrical conductivity of an aqueous solution. It is ideal for investigating the properties of solutions, including total dissolved solids (TDS) for water quality inquiry.



• Measure conductivity and total dissolved solids
• Automatic temperature compensation
• Battery life >1 year
• Remote logging with built-in memory
• Dust-proof, sand-proof, and water-resistant (1 meter for 30 minutes)

• Water quality investigations
• Performing condumetric titrations
• Investigating solution properties
• Diffusion of ions through membranes
• Differences between ionic and molecular compounds
• Comparing strong and weak acids

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.
