1 PRODUCT PRESENTATION
1.1 FUNCTIONAL PURPOSE OF THE UNIT
The basic system for pH and temperature measuring is made of three parts:
-the meter described in this instruction manual;
-a pH
-a Pt1000 temperature sensor
The instrument has the necessary electric circuits and firmware to perform the following functions:
1) as the proper sensor is connected, it displays the pH and temperature values;
2) if a Pt1000 temperature sensor is connected, it will display the temperature values;
3) it performs an automatic or manual temperature compensation for pH measures;
4) it performs the manual or automatic pH calibration
5) it allows the memorization and the visualization up to 100 readings
1.2 FUNCTIONAL PRINCIPLES
When measuring pH, the instrument receives a mV signal from the sensor and it displays the value
in pH units; this is done according to Nernst’s law and the sensor used.
It is possible to make the necessary zero and sensitivity adjustments for pH and the zero adjustment
for temperature.
Temperature influences the solution’s ionic activity and the signal provided by the pH sensor.
For this, in applications where the liquid temperature is different from a reference value of 20 °C, it is
important to use the temperature compensation function of the pH measuring.
In applications where there is a great variation of the temperature value, it is recommended to
consider using a RTD and to use the automatic temperature function.

3.3 HOW TO READ THE INSTRUCTION MANUAL
The manual includes all necessary information to fully comprehend the product, to use it and
preserving it, and finally to achieve the performances for which you have selected it and purchased it.
The manual is intended for experienced and prepared personnel, who has knowledge of electronic
instrumentations for field application.
The index guides the reader through the chapters and through the contents that he wishes to know or
exploit.
In particular, the first chapters narrate the general characteristics and they allow the reader to
become more familiar with the product by describing its accessories and its use.
The user can then verify if he/she has the necessary know-how to use the meter.
Note
Maintenance staff could be more interesting in the chapters regarding:
-users instructions;
-calibration;
-maintenance;
-warranty/repair terms and conditions.
3.3.1 USING THE INSTRUMENT ON THE FIELD
The end user can operate the meter by reading the pH/temperature and eventually recording up to
100 readings through the three keys on the front panel.
3.3.2 PLANT MAINTENANCE STAFF
Maintenance staff can select and set the desired parameters of the “set up” menu and perform the
calibration of the measuring by using the standard solutions.
The set-up menu allows the selection of:
-the response time value of the filter software;
-the °C/°F temperature measuring unit;
-the auto switching-off time:

4.0 SPECIFICATIONS
4.1 FUNCTIONAL SPECIFICATION
Display
The instrument has an alphanumeric LCD display 8x1 characters.
The display shows the measures values and the messages to the operator.
After the switching-off time the display will switch off automatically.
Keyboard
The instrument has 3 keys that perform a second functions when pressed for more than 3 seconds.
Input
The meter can be connected to a pH sensor provided with a BNC connector.
If it is connected to a temperature PT1000 sensor, the meter can provide °C or °F readout.
pH temperature compensation
When measuring the pH and the temperature, the meter performs the automatic temperature
compensation.
When the temperature sensor is not connected or it is malfunctioning, the meter performs the pH
manual temperature compensation. The temperature display will show the messages °CM or °FM and
the manual value.
Calibration
During the pH calibration, the meter recognize automatically the Nieuwkoop buffer solution
pH 4.01 –pH 6.86.
Power supply
The meter is operated by a 9VDC battery.
Instrument setup
The meter has the set up menu to select, the response time of the filter software for small signal
variations, the temperature °C/°F measuring unit and the time of the automatic switch off.
Data logger
The meter can memorize up to 100 pH and temperature measures. At the end of the calibration
procedure it is possible to enter the date of the last calibration.
