pH/ORP-meter industrial two channel for nuclear power plants
The pH-meter for NPP is designed for use in severe environmental conditions, namely on seismic resistance,
climatic conditions, radiation resistance, difficult situation for electromagnetic compatibility (EMC).
PH-meter 4122.NP is a two-channel analyzer consisting of one or two primary transducers (PT) and a
measuring instrument (MI).
PT consists of an electronic unit and a pH electrode,
which is fixed in the holder.
PT electronic unit enclosure is made of stainless steel,
which enables to make its processing with decontamination fluids.
The pH meter has a user-friendly menu and provides digital indication of pH,
emf and temperature values, converting them into proportional values of unified output DC signals,
data exchange via digital RS-485 interface (ModBus RTU exchange protocol),
signaling the output of measured parameters beyond set values,
as well as archiving and graphical display of measurement results.
pH-meters for NPP are designed in two versions:
monoblock – PT electronic unit is mounted on the holder;
separate – for use in the radiation zone
PT electronic unit is mounted separately from the holder up to
20 meters in a protected room. PH-electrode is connected to the PT with a special connector with a cable. This
allows to provide a quick replacement of the sensor in the rooms with a nuclear radiation.
Areas of application: nuclear power, as well as other
industries where super reliable measurement of the activity of hydrogen ions (pH) in harsh operating
conditions is required.
