Storing the electrode in the provided plastic tube
• Screw the sealing cap off the plastic tube. Keep it in the original packaging.
• If there is not enough KCl solution in the plastic tube, fill it up with 3 molar KCl solution.
• Insert the electrode tip through the hole in the storage cap (see drawing on page 13).
• Carefully push the O-ring delivered with the storage cap on the electrode so that the cap sits
over the O-ring.
• Insert the electrode tip into the plastic tube until it is fully covered with KCl solution.
• Tighten the cap.
• Store the electrode in its original packaging.
3.3 Installation procedure
Because a new pH electrode needs to be calibrated before it is installed into its final measuring
location, it is important to follow the installation order:
1. Unpack the electrode.
2. Connect the electrode to the signal converter.
3. Calibrate the electrode.
4. Install the electrode into its final measuring location.
The required steps are explained in the following sections.
