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