Audible Liquid Level Indicator blue (Please seek ROVI support if using this item for the first time)

Description

A compact, lightweight device with three metallic probes used to give indication of two separate liquid levels within a cup or mug; giving off audible signals. With a built-in magnet it can easily be stored on your fridge door when not in use.
A damp cloth can be used to clean the probes but note that the unit must never be immersed in liquid as they are not sealed and damage to the electronics will result.
Prior to each use it is recommended that you test the unit with cold water to ensure that there is sufficient battery capacity for the device to operate properly.
