DULCOTEST® redox measurement sensors


Redox measurements with DULCOTEST® sensors

Typical measuring range -1,500 to +1,500 mV; wider ranges are possible depending on the measuring instrument. Accurate and reliable values in real time. They can be used both in water treatment and in the control of industrial process water with high requirements.

Redox measuring sensor

The DULCOTEST® range of pH redox sensors offers a wide range of sensors to tackle your measurement tasks. Applications range from simple water treatment operations to industrial process water with high demands on temperature, pressure, fouling resistance and chemical resistance.

The production of our electrodes is subject to the strictest quality control, which is performed automatically during normal stages and controlled manually during critical stages. This allows the optimum level of reproduction quality to be achieved and is cost-effective.

The redox potential is a measurement that can quantify in a non-selective way the presence of a reducing or oxidizing agent in an environment under certain circumstances. Measuring this parameter is relatively inexpensive, but it also has some limitations. If a particular reducing/oxidizing agent is not selectively determined, the pH dependence will be very strong and the measured signal will shift over the saturation curve at higher concentrations. Corresponding amperometric sensors (such as chlorine sensors) are used to selectively measure various reducing and oxidizing agents without the advantages mentioned above.

Product advantages

  • Accurate measurement enables efficient and safe processes.
  • Wide range of sensors with different designs allows reliable application in different fields.
  • The high quality of the measuring electrodes and diaphragms together with the stable reference system ensure a long product life.
  • Short storage times and short delivery times make it possible to take full advantage of the shelf life of the pH sensors (aging of glass sensors begins immediately after production).
  • Tailor-made integration into the process by means of special versions of mounting length, cable length and connectors.

Fields of application

  • Cyanide detoxification in case of elevated pH value by oxidation
  • Detoxification of chromate in case of low pH value by means of reduction
