<p>A device for detecting cation saturation in an ion exchange filter includes electrodes disposed in an interchanging resin. One of the electrodes receives power from a source of supply, while the other electrode picks up a cation potential signal and through a tracking circuit comprising an operational system informs a comparator circuit having a fixed threshold valve which operates depending on the value emitted by the tracking circuit, activating a luminous and/or acoustic alarm system, all of which is optatively activated by means of a manually operated push-button.</p> |
