Product Description

SE 656 Toroidal Conductivity Sensor

Special and precise sensor with high chemical resistance over a very large measuring range, for heavily polluted and strongly oxidizing media

Corrosion-resistant toroidal sensor for measuring pure water up to maximum conductivities. Insensitive to strongly oxidizing media. Smooth, easy-to-clean design.
High accuracy due to electrodeless measurement.
Low risk of contamination because of large sensor opening.
Also suitable for hazardous locations.

SE 656 Toroidal Conductivity Sensor Applications
Conductivity measurement of highly concentrated acid and alkaline solutions, hydro-fluoric acid, nitric acid, concentrated sulfuric acid, oleum, concentrated alkaline solutions, strongly oxidizing media

SE 656 Toroidal Conductivity Sensor Facts
 - Robust design
 - Extremely large measuring range due to inductive measuring principle
 - Insensitive to contamination
 - No process-wetted electrodes
 - Extremely high chemical resistance (PFA)
 - Measurement in hazardous locations
