Beschreibung
Zusammenfassung:	An apparatus for precisely monitoring the effectiveness of a reverse osmosis water purification system is disclosed which continuously measures and compares the electrical conductivities of the impure aqueous solution and the purified water on the inlet and outlet sides, respectively, of the semipermeable membrane of the reverse osmosis system. A meter provides a visual indication of the comparison which is preferably related to the ratio of the outlet side conductivity to the inlet side conductivity and a fail-safe alarm signals when this ratio exceeds a selected level. The meter may be scaled so that during a normal operating mode of the apparatus it indicates the actual ratio of the impurity levels of the outlet and inlet sides and during a test mode it indicates a selectable alarm point.
