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. Typical applications processes with elevated continuous temperatures sterilization applications measuring points requiring reliable pH monitoring under thermally demanding conditions fluoride-containing media up to 1000 mg HF/l

If you are looking for a pH electrode for hot process conditions and value HT glass, hole diaphragm, high-temperature gel, and a salt reservoir, this JUMO tecLine version is an excellent choice. JUMO tecLine pH electrode with glass shaft, high-temperature gel, hole diaphragm, Pg13.5 screw head, 120 mm and salt reservoir This 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. The combination of HT glass, high-temperature gel, hole diaphragm, and salt reservoir makes this version especially relevant for applications where high temperatures and more challenging media occur together. Technical data Basic type: glass shaft Active element: HT glass Measuring range: pH 0 to 14 Temperature range: 0 to +135 °C Diaphragm: hole diaphragm, gel made of polymerized solid electrolyte (“diaphragm-less”) Electrical connection: Pg13.5 screw head (S8) Reference system: high-temperature gel, sealed, cartridge reference system Immersion length: 120 mm Type extension: salt reservoir (837) Advantages of this version A key advantage of this electrode is its suitability for temperatures up to +135 °C. This makes it especially relevant when pH measurements must remain reliable not only under normal conditions but also in permanently hot or thermally demanding processes. The HT glass is designed for the full pH range from 0 to 14 and is specifically developed for high-temperature applications. This makes the electrode a suitable solution for thermally demanding industrial processes. Why choose this electrode? This version is particularly suitable when, in addition to temperature resistance, a robust solution for more demanding media is required. The hole diaphragm with gel made of polymerized solid electrolyte is designed for applications where conventional diaphragms may clog or become contaminated more quickly. This ensures reliable operation even under difficult conditions. The salt reservoir is an additional advantage when longer service life is required, especially in challenging processes. The high-temperature gel and sealed cartridge reference system complete this robust, process-ready design. With the Pg13.5 screw head (S8) and 120 mm immersion length, the electrode can be integrated into many standard measuring setups. The combination of high-temperature resistance, clog-resistant diaphragm design, and salt reservoir makes this version particularly suitable for applications where both temperature and media place higher demands on the electrode.
