GENERAL

pH measurement is used in chemical industry, in swimming pools, potable and wastewater treatment and also in different kinds of industrial measurements.

Controlmatik probe M 1122 is designed for continuous measurement of pH in swimming-pools, 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

· 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 manual or automatic temperature compensation (depends on customer request) and with 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.
