The pH meter of pH-4121 type is designed for automatic measuring of the hydrogen ions activity (pH)and temperature (T) of the analyzed liquid complete with flow or submersible holders for a combined electrode.

   pH-meter provides measuring and convertion values to standard analog output DC signals, data exchange with a computer via digital interface, alarming the measured parameters overranging the specified values.

   pH-4121 consists of primary transducer (PT) and and measuring instrument (MI). PT consists of holder, in which a pH electrode is installed, and an electronic unit.

   The instrument calibration according to the buffer solutions is performed in the primary transducer.

   4121.E.I-Ех pH-meters (in the «I» enclosure) have an explosion protection type provided with a marking «1Ex d IIB Т6 Х».

   pH-meter with an ”E” index complies with raise requirements on electromagnetic interference resistance.

   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;
