3.7 Installing the sensor
3.7.1 General installation instructions
The electrode tip must always have full contact with the measuring medium.
The mounting position of the electrode should not deviate more than 75° from vertical position
(electrode tip pointing downwards). Doing otherwise might cause internal air bubbles to float
into the electrode's glass tip. This would interrupt the electrical contact between the inner buffer
solution and the glass surface.
