The Opti range of hand-held digital refractometers allow you to analyse samples quickly and accurately.
This refractometer is used to determine the percentage ABV.
Please note, before you use the refractometer, you will need to measure the Specific Gravity of your product via a hydrometer (see link below). 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. See Application & Downloads for more information.
Scale A: Brix
Scale B: °Zeiss: NB: The refractometer must be set to Scale B to give the Zeiss value used to calculate ABV
