Abstract
PURPOSE: To make the circumference of said electrode always clean and operate the measuring apparatus for components contained in liquid always accurately, by applying the voltage pulse of the polarity opposite from the voltage polarity at the measurement at every predetermined time.
CONSTITUTION: A voltage is applied from a measurement circuit M to an electrode S in order to examine the conductivity of liquid. A timer T produces outputs at the time intervals determined by setting, for example, 2W12hr, and these outputs are applied to a pulse generator PG. Every time when the pulse generator PG receives the output from the timer T, it applies a one-shot pulse to a polarity change-over device PC. The polarity change-over device PC is inserted in the route of applying a voltage from the measurement circuit M to the electrode S, and inverts the polarity of said route. Thereby, the + pole and - pole of the electrode S are connected to the polarities opposite from the polarities up to then once every 2W12hr.
