A symmetrically wired device and a process for measurement of the concentration of ions, especially hydrogen (H+) ions, in a measurement liquid. The device comprises a pH-sensitive measurement electrode, a reference electrode and a comparison electrode, all located in the measurement liquid and which places the measurement liquid at a definable ground reference. The device forms a difference signal referenced to the ground reference from the difference between a measurement signal (&#x3c6;pH) of the measurement electrode and the reference signal (&#x3c6;ref) of the reference electrode. The difference signal is dependent on the ion concentration in the measurement liquid. The device compensates for the noise potential (&#x3c6;chem) arising between the comparison electrode and the measurement electrode by setting a reference potential (&#x3c6;bez) on the comparison electrode, such that &#x3c6;ref assumes a zero value.

A design for constructing an input circuit to receive and process an electrical signal, such as a voltage signal from a voltage source, where the input circuit has an extremely high resistance of at least 10 ohms and is located on a printed circuit board. A first area of the printed circuit board carrying components of the input circuit is separated from a second area surrounding or contiguous to it by a channel-shaped recess to preserve the high resistance of the circuit even under operating conditions and at high relative humidity. The circuit is configured in such a way that the channel-shaped recess terminates in the interior of the printed circuit board and is extended in the direction of the thickness of the printed circuit board immediately up to a moisture-impermeable barrier layer which underlies the first area of the printed circuit board. The channel-shaped recess and the first area are filled and surrounded by a cohesive moisture-impermeable material.
