SmartRef - Digital refractometer

SmartRef Digital Refractometer can determine original and final gravity with automatic wort and alcohol correction. With a small sample volume of only 0.4 mL, the SmartRef delivers accurate results with automatic temperature compensation (ATC).

SmartRef can be used for determining the extract content of wort, the alcohol content of wine, the sugar content in fruit juices, the sugar or water content in honey, the total dissolved solids in coffee, the alcohol content in spirits (containing no added sugar), salinity in salt water aquariums and many more applications. If used with the EasyDens density meter, it is also possible to measure the alcohol content of liqueur and sugar-containing spirits.
