pH-meter is a two-channel measuring device consisting of two primary transducers (PT) and a measuring instrument (MI). MI of the instrument is of panel or wall mount design.

   Two-channel рН-meter of type рН-4122 is designed for automatic measuring of the hydrogen ions activity (pH) or redox potential (ORP) and temperature (T) of the analyzed liquid. PT consists of holder, in which a pH electrode is installed, and an electronic unit.

   The analyzer has a user-friendly menu and provides a digital and graphical display of the measured values of pH and temperature, or OPR and temperature, their proportional conversion to standard analog output DC signals, data exchange with a computer via digital interface RS-485 (Modbus RTU data communications protocol), signaling the measured parameters overranging the specified values, as well as archiving and graphical display of measurement results.

   рН4122.I-Ех pH-meters (in the «I» enclosure) have an explosion protection type "flameproof enclosure" provided with a marking "1ExdIIBТ6 Х".

   Scope of application: heat power industry, chemical, petrochemical, food processing, brewering and other industries.

   Accessories:

• combined pH-electrodes;
• holders for рН-electrodes;
• pH-metric cable;

• Modbus-configurator
• Modbus OPC server
