Fill your cup with greater confidence using RNIB's Liquid Level Indicator. Simply place this gauge on the side of a cup, glass or jug and the sensors will let you know when the liquid gets to the top, through a series of beeping sounds and vibrations. Suitable for use with both hot and cold liquids. Use this liquid level indicator when filling up a kitchen pan, pot, or mug.

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 and vibratory 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 liquid 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.
