Abstract: An invention is provided for encouraging routine testing for TDS levels in a liquid. The invention includes a conductivity sensor capable of sensing a conductivity level of a liquid, and a processor in electrical communication with the conductivity sensor. The processor has logic that calculates a TDS level for the liquid based on the conductivity level of the liquid. The calculated TDS level for the liquid is then displayed on a display in electrical communication with the processor. Also included is a speaker, which is electrical communication with the processor. To provide automatic reminders to the user, an integrated timing mechanism is included that is in communication with the processor. When a predetermined period of time has elapsed, such as the period of time between periodic TDS level testing, the integrated timing mechanism sends a signal to the processor to provide an alert to the user to test the TDS level.

Abstract: An invention is provided for encouraging routine testing for TDS levels in a liquid. The invention includes determining a TDS level of the liquid utilizing an apparatus capable of determining a TDS level based on the conductivity of the liquid. Next, corrective action can be performed to reduce the TDS level when the TDS level is beyond a predetermined level. To facilitate a continual visual reminder for future TDS level testing, the apparatus is removably attached to a surface viewable when in proximity of a device utilized to access the liquid utilizing an integrated attachment mechanism.
