1 PRODUCT PRESENTATION
1.1 FUNCTIONAL PURPOSE OF THE UNIT
The basic system for chlorine/dissolved ozone monitoring is made of three important parts:
- the controller described in this instruction manual;
- the sensor;
- the flow cell.
The instrument has the necessary electric circuits and firmware to perform the following functions:
1) as the proper sensor is connected, it displays the chlorine/dissolved ozone concentration values;
2) if a Pt100 or Pt1000 temperature sensor is connected, it will display the temperature values;
3) it performs an automatic or manual temperature compensation;
4) if dosing pumps or solenoids are connected to the specific relays, it will automatically adjust the
conductivity values;
5) if the measure goes outside the low/high limit values, it will give an alarm;
6) it provides an analog output for recording and acquiring the chlorine/dissolved ozone values;
7) to receive an external free voltage contact that activates the alarm or the hold condition.
1.2 FUNCTIONAL PRINCIPLES
The measuring of the free chlorine, chlorine dioxide or dissolved ozone is done by means of two types
of sensors:
- polarographic cell with two electrodes immersed in the suitable electrolyte and with selective
membrane,
- potentiostatic sensor with three electrodes.
A polarization voltage is applied to the anode and cathode of the polarographic cell in order to get an
electrical current into the electrolyte, proportional to the chlorine/d.ozone concentration.
A polarization voltage is applied to the anode and counter electrode of the potentiostatic sensor in
order to get an electrical current into the sample, proportional to the chlorine/d.ozone concentration.
A reference electrode allows the compensation of the ORP and resistance effects.
As a result the measuring is very accurate even at low concentration levels.
The current through the polarographic or potentiostatic cell is effecting a chlorine/d.ozone
consumption, to be renewed by a constant liquid flow.
If the liquid is not regularly renewed the readout will decrease slowly to zero.
This instrument features a manual or automatic temperature compensation, referred to
temperature of 20 °C or 25 °C.
1.3 SENSORS AND ACCESSORIES
The listed articles are the most commonly used ones. They must be ordered separately.
