Go for green! The Attento is a thermo-label which you put on your frothing pitcher. The label has liquid crystal slots which indicate the accurate temperature by turning black from green. Faster than lightning A big issue with standard frothing thermometers is the delay. They are very often up to several seconds out of sync with the actual temperature of the milk. This is a natural effect of all probe thermometers. This is not a problem with the Attento. Liquid Crystals don't wait to turn green when a certain temperature have been reached, they react instantly! Always at hand Most bars have thermometers. In a drawer or a box with other less-used stuff.... Once you put the Attento on a pitcher it stays there for years to come, showing the temp of every latte you serve day in and day out. It is of course dishwasher safe. Finally you secure the quality of every latte drink you serve. Highly durable, professional quality. Dishwasher safe. Place on every pitcher and never burn you milk again!
