Product information "JUMO ecoLine glass shaft pH electrode with salt reserve, S8 Pg13.5 screw head"

This electrode is particularly suitable wherever a cost-efficient, proven, and long-life-oriented electrode is required for general aqueous media.

JUMO ecoLine glass shaft pH electrode with salt reservoir, S8 Pg13.5 screw head (type key: 201005/51-18-22-0000-00-120/837, part no.: 00447837)

This JUMO ecoLine glass shaft pH electrode is a reliable choice for pH measurements in general aqueous media. It is designed for users who are looking for an economical, practical, and robust electrode suitable for many standard water applications. The version with salt reservoir is particularly advantageous when the electrode is used under conditions where extended service life is beneficial.

Technical data

  • Design: glass shaft pH electrode
  • Measuring range: pH 0 to 12, short-term up to pH 14
  • Temperature sensor: none
  • Active element: JUMO UW glass
  • Diaphragm: ceramic
  • Electrolyte: polymerized KCl solid electrolyte
  • Reference system: JUMO cartridge reference system
  • Electrical connection: S8 Pg13.5 screw head
  • Immersion length: 120 mm (standard)
  • Type extension: salt reservoir

Advantages and special features

The electrode measures in the pH range from 0 to 12, and for short periods up to pH 14. It is equipped with low-ohmic JUMO UW glass, enabling fast and stable measurement results. The ceramic diaphragm and polymerized KCl solid electrolyte make it suitable for many standard applications in water analysis.

The proven JUMO cartridge reference system ensures that the electrolyte remains free of silver ions over its service life and is less susceptible to certain electrode poisons.

Why choose this electrode?

This version is particularly suitable when a pH electrode for general water applications is required that offers more than a basic standard model. The salt reservoir is especially beneficial in low-ion media or higher flow conditions, as it can extend the electrode’s service life.

For this reason, it is ideal for users seeking a more durable solution for regular operation rather than a basic version without additional type extensions.

With the S8 Pg13.5 screw head and 120 mm immersion length, the electrode fits many common installation situations. An integrated temperature sensor is not available in this series, keeping the focus entirely on reliable pH measurement.

KCl container (quiver), extra code 052 Salt deposit, extra code 837
see product images The foot of the KCl container can also be used as a mounting spanner for pH or redox electrodes with Pg13.5 thread. The recesses on the removable container foot fit the hexagon of the electrode head. When storing the electrodes, the container must be filled with KCl (not with buffer solution or similar). see product images As an option, the electrode can be equipped with a salt reservoir in the form of four salt rings. This is recommended when using the electrode in media with low ion content or at high flow rates. The salt reserve serves to increase the service life of the electrode. The rings do not represent a manufacturing defect (crystallisation).
