Designed for single handed operation the SENSA is simply hung on the rim of the cup, mug or glass.
It automatically adjusts itself for different types and sizes of container.
Pour in the milk and a tone sounds for several seconds when the level reaches 1/2" from the bottom.
Add water and the tone sounds continuously when the level reaches 1/2" from the top.
Equally useful for a single liquid - just ignore the first tone.
Smooth hygenic wipe clean surface with no sharp probes or exposed wires.
