General:
pH 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 1122 is designed for continous measurement of pH in swimmingpools, potable, waste and industrial waters. With special versions of measuring electrodes it can also
be used for measurement of other media.
The unit consists of pH measuring electrode and 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 manual or automatic temperature compensation
(depends on customer request) and with SELECAN communication output or with the galvanicly
separated 4–20 mA signal on the amplifiers output. The user can easily communicate with a probe
over graphic display and four function keys.
All this guarantees accurate and continuous measurement.
