Conductivity Sensors

Knick’s conductivity sensors offer all measuring principles: 2-electrode, 4-electrode, and inductive. The analog and digital conductivity sensors cover a wide range of measurement requirements, from ultra-pure water to highly concentrated acids and alkaline solutions, and they are available with explosion protection.

The sensors are compatible with inline, flow-through, and immersion fittings, guaranteeing versatility in a variety of installation configurations and applications.
