Advantages and special features of the JUMO tecLine redox electrode

A key advantage of this version lies in its high-quality design for use in more demanding process environments. The gold tip makes this electrode particularly suitable for applications where appropriate redox measurement technology is required for specific process conditions. Especially in industrial applications, it is important that the electrode not only measures reliably but is also designed for regular use at the measuring point. This version is specifically intended for such requirements.

Why should you choose this JUMO electrode?

This version is particularly useful when a high-quality industrial electrode for process and industrial applications is required. The glass shaft represents a proven design in industrial environments, while the zirconium dioxide diaphragm ensures a robust and process-suitable construction. The additional salt reserve can help extend the service life of the electrode, which can be a practical advantage during continuous operation. This makes the version particularly suitable for users looking for a durable and long-lasting solution for their redox measurements.

The connection side is also designed for professional use. The Pg13.5 screw head (S8) enables a suitable connection to compatible measuring technology. With an installation length of 120 mm, this redox electrode is suitable for many common measuring points. Together with the high-quality design, this results in an electrode intended for reliable operation in typical process and industrial applications.
