Refractometer
A refractometer is a tool used in cafes and coffee shops to measure the quality and concentration of liquids. Think of it as a quality control tool that helps baristas ensure their drinks are consistent. For coffee, it measures how much dissolved coffee is in the brew, helping ensure each cup meets standards. It's also used for other beverages like juice concentrates or syrups. This tool is becoming increasingly important in specialty coffee shops where precision and quality control are priorities. It's similar to a thermometer in terms of being a measurement tool, but instead of temperature, it measures dissolved solids.
