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.
