Abstract

Method for automatically with the aid of a processor determining a surface degeneration of a first surface of a urine handling system the first surface being intended to come into contact with urine the method comprises the following main steps: a) repeatedly measuring one or more capacitive values of the first surface forming capacitive measurements; b) storing all or representative instants of the capacitive measurements; c) deciding based on changes of the stored capacitive measurements that a significant surface degeneration of the first surface has occurred
