Product Specification

SE 680 Toroidal Conductivity Sensor

High-precision sensor made of FDA-approved PEEKwith an extremely large measuring range. Steam-sterilizable.

The joint- and gap-free, sealless design and stain-resistant surface made of Virgin PEEK make the SE 680 a heavy-duty sensor. The inductive technology is not influenced by polarization and does not have any sensor surfaces subject to corrosion.

SE 680 Toroidal Conductivity Sensor Applications

Fresh water technology, dairy products, breweries, soft drink manufacturing, electroplating, air-conditioning, CIP monitoring in the beverage industry, pharmaceutical applications, cooling tower monitoring, on-site wastewater treatment plants, monitoring concentrations of salt solutions, alkalis and acids, washers, and rinsing processes
