ABSTRACT:
An apparatus allows monitoring the formation of scale. The apparatus makes it possible to determine the degree of water hardness or a tendency of the degree of water hardness to change over time and to take measures for adjusting the desired degree of water hardness accordingly. A translucent or transparent element has two end surfaces, at least one element emitting an optical signal, and at least one element receiving an optical signal. The element emitting the optical signal and the element receiving the optical signal are directly adjacent to the end surfaces of the transparent element, and the end surfaces are disposed such that they remain free of scale build-up at all times.
