2 PRODUCT OVERVIEW
2.1 FUNCTIONAL PURPOSE OF THE DEVICE
The system for monitoring pH and ORP consists of two main parts:
• the meter/regulator described in this instruction manual;
• a probe/measuring electrode.
The instrument contains the electronic circuitry and firmware to perform the following
functions:
• display the measurement values of pH or ORP of aqueous solutions, with an appro-
priate sensor connected;
• view of the temperature values, if a temperature sensor Pt100 or Pt1000 is connect-
ed;
• perform the automatic or manual temperature compensation of pH measurements;
• automatic control of pH or ORP, if the output relays are connected to appropriate
metering pumps or solenoid valves;
• provide an alarm if the measuring exceeds the minimum or maximum limits estab-
lished of if relays remain activated for more time than established;
• provide two output signals for recording or the acquisition of pH or ORP measuring
values;
• acquire external contacts to activate the alarm or keep the instrument in hold;
• enable automatic or manual cleaning cycles when connected to appropriate devic-
es.
Pumps or valves can be activated directly by the instrument or by external control
switches if their power load is not compatible with the instrument's relays.
