3.4 Performing a Standard Titration
For most users, the default settings programmed into the smartCHEM-Titro will result in fast,
reproducible titrations. However, some variables may be altered by the user to speed up the process,
avoid overshooting etc. See section 3.3.1 for details on changing the Titration Parameters.
Press at any time during the titration procedure to abort the titration.
1. When the smartCHEM-Titro is in Standard Titrator mode, the following display is shown in
normal display mode…

STD Titration
If the Automatic Datalogging function is programmed (as per section 12.2), an additional
prompt informs you that the titration curve will be logged into memory. For example…

2. Place the pH and Temperature sensors into the sample. The reference
junction of the pH sensor must be immersed, as per the diagram.
The burette dosing tip should be immersed to the same level as the green
bulb of the pH sensor. It is best to mount this upstream from the pH
sensor when the stirrer is running.
