Dual Sound Liquid Level Indicator



This liquid level indicator is a great tool for the kitchen! Tired of accidentally overfilling your glass or mug and having to clean up a mess? This product will warn you with steady beeps when your beverage gets within 1 1/4" of the rim, and then shifts to a solid tone when you're 3/4" away from the rim. No more messes! No more burning your fingers! Uses one 9 volt battery (included.)
