Fill your cup with greater confidence using RNIB's Audible Liquid Level Indicator. Simply place it on the side of a cup and a series of audible beeps will let you know when the liquid nears the top.

Kimberly talks about the liquid level indicator, view below:

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. This can be used to assist in filling a cup with hot water/tea/coffee until the first level is reached and then topping up with milk until the second liquid level is detected. With a built-in magnet, our best-selling liqud level indicator 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.

Battery supplied (CR2032).
