Your benefits
  • With patented KNO 3 electrolyte bridge for better protection against electrode poisons such as S 2- or CN ions
  • Optionally available with flat membrane for improved wear resistance
  • Threaded connection NPT 3⁄4" top and bottom for easy installation at user end
  • Suitable for measurements within pH range 0 to 14 and within temperature range to 110 C (32 to 230 F)
  • Digital pH sensors with integrated temperature sensor, analog pH electrodes with or without integrated temperature sensor
  • Protection guard against damage
Other advantages of Memosens technology
  • Maximum process safety owing to non-contact, inductive signal transmission
  • Data security thanks to digital data transmission
  • Very easy to use as sensor data saved in the sensor
  • Predictive maintenance possible as sensor load data logged in the sensor
Measuring principle (pH measurement)

The pH value is used as a unit of measurement for the acidity or alkalinity of a liquid medium. The membrane glass of the electrode supplies an electrochemical potential which is dependent upon the pH value of the medium. This potential is generated by the selective penetration of H + ions through the outer layer of the membrane. An electrochemical boundary layer with an electric potential forms at this point. An integrated Ag/AgCl reference system serves as the required reference electrode. The transmitter converts the measured voltage into the corresponding pH value using the Nernst equation.

Measuring principle (ORP measurement)

The ORP potential is a unit of measurement for the state of equilibria between oxidizing and reducing components of a medium. The ORP is measured using a platinum or gold electrode instead of the pH-sensitive glass membrane. Analog to the pH measurement, an integrated Ag/AgCl reference system is used as a reference electrode.

Measuring system

A complete measuring system comprises:

  • Sensor CPF81D, CPF81, CPF82D or CPF82
  • Transmitter,e.g. Liquiline CM44x/R or Liquiline M CM42
  • Measuring cable, e.g. CYK10 or sensor's fixed cable
