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.
