Ideal for cup, glass or mug. Designed to assist those with a visual impairment, this ingenious device helps the user to pour liquid into a container, confident that they will not overfill and cause a spillage. The Indicator is easily hooked onto the side of a cup, glass or other container and emits two distinct tones to indicate the level of liquid contained in it. An intermittent tone indicates that the cup is nearly full and a continuous tone indicates it is full. Supplied in bright yellow and includes 3V cell batteries. RNIB approved.
Dimensions L48 x W35mm (2 x 1").
