Product description

Online measurement of electrolytic conductivity – with the reliable DULCOTEST® sensors.

Conductive conductivity Conductive conductivity sensors measure the electrolytic conductivity indirectly via ... more in the glossary sensors measure the electrolytic conductivity indirectly via the charge transfer between two probes immersed in the medium to be measured. The sensor types with cell constants k = 0.01 and k = 0.1 cm-1 are especially suitable for measuring the lowest electrolytic conductivities of < 1 µS/cm in pure and ultra-pure water.

The sensor types with cell constants k=1 cm-1 are used in numerous kinds of water without film-forming components up to 20 mS/cm. The cost-effective sensor range LF(T) is used in clear, chemically uncontaminated water.

The sensor ranges LM(P), CK and CKPt can also be used in chemically contaminated kinds of water and at higher temperatures.

  • 27 different sensor types tailored to different requirements and offering optimum performance for money: measuring range, temperature, chemical resistance, contamination tolerance and process integration
  • From simple conductometric sensors to high-end sensors based on the inductive measurement principle
  • Precise and reliable measurement enables efficient processes and maximum process reliability
  • Long service lives and short maintenance intervals reduce downtime and increase the availability of the measured values
  • Complete pre-assembled kits containing fitting and sensor for easy, fast and error-free installation
  • Prompt delivery for quick replacement

    Overview

    Online measurement of electrolytic conductivity – with the reliable DULCOTEST® sensors.

    Conductive conductivity Conductive conductivity sensors measure the electrolytic conductivity indirectly via ... more in the glossary sensors measure the electrolytic conductivity indirectly via the charge transfer between two probes immersed in the medium to be measured. The sensor types with cell constants k = 0.01 and k = 0.1 cm-1 are especially suitable for measuring the lowest electrolytic conductivities of &lt; 1 µS/cm in pure and ultra-pure water.

    The sensor types with cell constants k=1 cm-1 are used in numerous kinds of water without film-forming components up to 20 mS/cm. The cost-effective sensor range LF(T) is used in clear, chemically uncontaminated water.

    The sensor ranges LM(P), CK and CKPt can also be used in chemically contaminated kinds of water and at higher temperatures.

    • 27 different sensor types tailored to different requirements and offering optimum performance for money: measuring range, temperature, chemical resistance, contamination tolerance and process integration
    • From simple conductometric sensors to high-end sensors based on the inductive measurement principle
    • Precise and reliable measurement enables efficient processes and maximum process reliability
    • Long service lives and short maintenance intervals reduce downtime and increase the availability of the measured values
    • Complete pre-assembled kits containing fitting and sensor for easy, fast and error-free installation
    • Prompt delivery for quick replacement
