- Fruits & Honies: Used for testing the ripeness of fresh fruits such as grapes and tomatoes simply by squeezing a small amount of juice directly onto the refractometer prism. OPTi refractometers are used in the manufacturing of jam, marmalade, syrup and other high sugar content products as well as quickly testing for moisture in honey direct at the hive. They are ideal for testing finished juices and other soft drinks. Scales include: Brix, °Butyro, HFCS, Salinity, Water in Honey, and more - see image chart
- Beer: In breweries refractometers are used to measure Wort prior to fermentation as well as determining alcohol content*.
- Wine: In vineyards, grape ripeness can be checked before harvest, sugar content assessed, and ABV content (measured by way of the Zeiss scale and hydrometer) in the final stages of production*. Scales include: Brix, Wort SG, °Baume, Alcohol Probable, Oechsle - see image chart. Before you use the refractometer, you will need to measure the Specific Gravity of your product via a hydrometer (see link below).
(*) Determining alcohol by volume (ABV): Before you use the refractometer, you will need to measure the Specific Gravity of your product via a hydrometer (not included). The alcohol content is determined by a calculation involving the refractometer reading and the Specific Gravity reading. Enter the readings into the online calculator to give you the alcohol content, or do the calculation yourself and look up the resulting value in the table supplied to get the alcohol content.
