pH 

To perform the calibration of the pH electrode assembly / pH meter SENSOGLASS proceed: 

1 - With the pH meter in operation press the MENU button; 

2 - The first menu option is "Set pH", press YES to confirm; 

3 - Rinse the electrode with deionized water and wipe lightly with absorbent paper; 

4 - You will be asked to immerse the electrode in the buffer solution of pH 7.01; 

5 - Activate the SIM screen; 

The device will indicate on the display that it is processing the measurement. At this point a 30-second countdown will start and as soon as the pH sensor stabilizes, the pH meter will move to the next calibration point.

6 - Rinse the electrode again with deionized water and wipe lightly with absorbent paper; 

7 - Immerse the pH electrode in the required buffer solution (pH4.01 or pH10.01); 

8 - Activate the SIM screen; 

9 - After a few moments the display will indicate a message with the SLOPE of the electrode, for example: 
SLOPE OF THE ELECTRODE 98% This percentage indicates the life of the electrode assuming that the buffer solution is not contaminated. 9 - Press YES to end the calibration procedure and start your measurements. 


ORP 


To perform the ORP / pH meter electrode calibration, proceed as follows: 

1 - With the pH meter in operation press the MENU key;

2 - Search for the function "Set ORP" and press YES to confirm; 

3 - Rinse the electrode with deionized water; 

4 - Immerse the ORP electrode in the buffer solution 220mV;

5 - Activate the SIM screen; The device will indicate on the display that it is processing the measurement. At this point a 30 second countdown will start and as soon as the ORP sensor stabilizes, the pH meter completes the calibration. 

6 - Press YES to end the procedure and start your measurements. 


CONDUCTIVITY 


In the calibration of a conductivity meter it is necessary to know the constant (K) of the cell used and the standard calibration solution. Always use conductivity standards as close as possible to the constant (K) of the cell.

To carry out the calibration of your conductivity / conductivity cell, proceed as follows: 

1 - With the conductivity meter press (MENU) and navigate with the RIGHT / LEFT ARROWS on the equipment panel, and search for "Calibration Solution"; 

2 - Press YES to confirm; 3 - Adjust the value of the conductivity solution that will be used in the calibration, press YES; 

4 - Then adjust the Temperature Coefficient (CT), usually 2.2 and press YES; 

NOTE: It is not necessary to inform the value of the constant (K) of the Cell, since it will be calculated and updated by the conductivity meter itself. 

5 - With the RIGHT / LEFT ARROWS, look for the "ADJUST CONDUCTIVITY" function; 

6 - Press YES to confirm;

7 - Immerse the conductivity cell in the chosen standard solution; 

8 - Press YES again; 

8 - Wait for the calibration process to complete and at the end press ESC to start your measurements.
