Product information "JUMO tecLine pH electrode (glass shaft + high-temperature gel, 1x zirconium dioxide, screw head Pg13.5, 120mm, without extra code)"

If you are looking for a pH electrode for high-temperature process conditions and value HT glass, high-temperature gel, a zirconium dioxide diaphragm, and a reliable standard version without additional options, this JUMO tecLine variant is a strong choice.

JUMO tecLine pH electrode with glass shaft, high-temperature gel, 1x zirconium dioxide diaphragm, Pg13.5 screw head and 120 mm immersion length

This JUMO tecLine pH electrode is designed for demanding pH measurements at elevated continuous temperatures. It is particularly suitable for processes where standard electrodes are exposed to higher thermal stress and therefore require a specially designed solution. With HT glass, high-temperature gel, and a zirconium dioxide diaphragm, this version is ideal for applications where temperature resistance and reliable measurement performance are essential.

Technical data

  • Basic type: glass shaft
  • Active element: HT glass
  • Measuring range: pH 0 to 14
  • Temperature range: 0 to +135 °C
  • Diaphragm: 1 x zirconium dioxide
  • Electrical connection: Pg13.5 screw head (S8)
  • Reference system: high-temperature gel, sealed, cartridge reference system
  • Immersion length: 120 mm

Advantages and special features

A key advantage of this electrode is its design for temperatures up to +135 °C. This makes it particularly suitable for applications where pH measurement must remain reliable not only under standard conditions but also in warm or continuously hot processes.

The HT glass is designed for the full pH range from 0 to 14 and specifically developed for high-temperature applications. This makes the electrode a durable solution for thermally demanding environments.

Why choose this electrode?

This version is especially suitable for processes operating at elevated continuous temperatures, where a standard pH electrode would not be sufficient. The high-temperature gel and sealed cartridge reference system are specifically designed for these conditions, ensuring stable and long-lasting performance.

The zirconium dioxide diaphragm further enhances measurement stability and complements the robust overall design. With the Pg13.5 screw head (S8) and 120 mm immersion length, the electrode can be integrated into many common measuring setups.

As this version is supplied without additional type extensions, it is particularly suitable for users seeking a clearly defined high-temperature standard solution without extra features.
