The conductivity of a liquid can be measured using the conductive or toroidal measuring principles. This video shows what it is about and how these measuring principles work.

Toroidal conductivity measuring system for hygienic applications

Smartec CLD132 is a measuring system for inductive conductivity in the food & beverage industry. The combination of a transmitter and a sensor is interference-free, easy-to-use and features a hygienic design that protects your products and processes from contamination. Moreover, Smartec CLD132 is equipped with a stainless steel temperature sensor that gives you an ultrafast temperature response for reliable measurement in separation applications.
