Liquid Level Indicator

This device can detect two different levels of liquid. When filling a cup, an intermittent tone indicates that the cup is nearly full and a continuous tone indicates that it is full. This permits you to pour coffee or tea to one level and to then add milk or cream to the second level. In both cases the liquid level indicator produces tones that make it useful to people with a visual impairment. It comes fitted with two small magnets that enable you to store on a refrigerator to easy access. Uses a CR2032 battery (included) that is easy to replace. If you prefer an indicator that vibrates to alert you that water has reached the level of the prongs, order DK-30.
