Does your cup runneth over? This liquid level indicator will help to prevent any overflows.
* Just place this little device over the rim of your cup and you will hear a loud, beeping sound as soon as any liquid comes into contact with small probes which sit inside the cup - beeping will increase in speed when closer to the top
* A liquid level indicator is a great tool for anyone having difficulty pouring liquid or helpful for anyone working in the food service industry
* This liquid level indicator vibrates as well as beeps, making it useful for those who may be deaf/blind, or for anyone unable to hear the audible indicator
* Batteries included [uses Four (4) L1154f batteries]
