Conductivity / Resistivity

GF Conductivity/Resistivity electrodes are designed to provide versatile installation and accurate sensing across a broad, dynamic range.

The GF Conductivity/Resistivity electrodes are suitable for a variety of applications ranging from high-purity water quality monitoring to weak acids and bases.


Easy-to-use sensors for process and pure water applications are available in two different families with a selection of electrode materials and process connections.

Accuracy and reliability

Two-electrode sensors are built with a controlled surface finish to ensure measurement accuracy and repeatability. Reliability is guaranteed thanks to individual testing of cell constant to ensure the highest possible measuring accuracy.

Sensor electronics

GF Signet 2850 Conductivity/Resistivity Sensor Electronics are available in various configurations for maximum installation flexibility and are also compatible with all GF Signet conductivity electrodes.

Wide range of applications

They are usable in multiple types of applications, from pure water treatment to cooling tower and boiler protection, salinity, aquatic animal life support systems and more.
