Beneficio para el cliente

Stable and reliable measured values
A newly developed hydrogel-shaped filling for reference electrodes – temperature resistant up to 135 °C, non-toxic, physiologically harmless, and ageing resistant – enables excellent measurement properties such as quick response performance and low diffusion potentials.

Low maintenance and robust
Dirt-repellent ring-shaped PTFE diaphragm prevents deposits and blockages. An internal pressure buffer ensures compensation of temperature-related volume changes in the reference electrode chamber and allows process pressures up to 13 bar.

Prolonged service life
Double chamber version with dual diaphragm partitioning prevents damage to the reference electrode by electrode poisons (e.g. sulphides, amines, or chromates). A salt reserve in the reference electrode increases the lifetime especially in media with low conductivity.

The advantages of electrodes with combined JUMO digiLine electronics

  • Fail-safe digital data transfer for optimal process monitoring
  • Modular system: for single measuring points and for establishing electrode networks
  • Plug and Play function when connected to transmitters from the JUMO AQUIS touch series. This facilitates the replacement of electrodes or the brief exchange of electrodes for calibration purposes.
  • Also suitable for use with the JUMO mTRON T automation system
  • Version with 4 to 20 mA output for integration into existing systems
  • JUMO digiLine electronics can continue to be used even when the electrode becomes worn
  • Easy and secure calibration in the lab



Chemical industry:

  • Process water, high process pressures up to 13 bar, broad temperature range up to 135 °C, and wide pH range from pH 0 to pH 14

Industrial wastewater engineering:

  • Process wastewater, wastewater with highly contaminated media (oily contents, electrode poisons)


  • Process water, media with electrode poisons (metal ions, complexing agents)

Power plants and waste incineration plants (flue gas scrubbing):

  • Wide pH range of pH 0 to pH 14, presence of fine ash particles

Sugar industry:

  • Consistent high temperature, presence of electrode poisons (e.g. sulfides)


JUMO tecLine HD electrodes are high-quality sensors for professional applications in process and industrial measuring technology. The high-quality materials and components are the distinguishing features of these electrodes. They are designed as combination electrodes (glass or metal/reference electrode in one shaft). A temperature probe can also be integrated as an option, depending on the type. Suitable versions are available to meet the most varied requirements. JUMO tecLine HD sensors represent the state-of-the-art for modern pH and redox electrodes. Each top-quality electrode is individually tested and supplied with a quality certificate.
