Redox probe with controller M 1322

Measuring range: from -2000 to +2000 mV

  • Online Redox measurement
  • PI regulation option
  • Communication output (SELECAN) or galvanically separated current output
  • IP 65 housing

GENERAL

Redox measurement is used in chemical industry, in swimming-pools, potable and waste water treatment and also in different kinds of industrial measurements.

 Controlmatik probe M 1322  is designed for continuous measurement of Redox. With special versions of measuring electrodes it can also be used for measurement of other media. 

The unit consists of :

Redox measuring electrode

Controller with graphic display 

Electronics evaluates and amplifies the measured potential. PI regulator that independently controls a certain process, can be build in a probe. The probe can be equipped with the galvanic separated 4–20 mA signal on the amplifiers output. The user can easily communicate with a probe over graphic display and four function keys. 

The probe  guarantees accurate and continuous measurement.
