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.

  • Use along with a hydrometer (available separately) to determine % ABV with +/-0.5% accuracy (see note below)
  • Designed with a special linear scale called 'Zeiss' which, unlike standard Brix models with a compressed low end of the scale, allows for more accurate readings at the all important, low end of the scale - ideal for wine makers & cidermakers and used by Trading Standards officers
  • Precise digital LCD readout
  • One of the smallest instruments of its type on the market
  • 1-20% ABV range
  • Simple to use – push button control
  • Automatically corrected for temperature
  • Manufactured in the UK

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.

  • 1: Measure the Specific Gravity using a hydrometer
  • 2: Using the refractometer, obtain the Zeiss value: fill the prism disc and press READ NB: The refractometer must be set to Scale B to give the Zeiss value
  • 3: To get the %ABV either enter the values on the online calculator or do the calculation (see Downloads) yourself and look up the resulting value in the table supplied
  • Allows you to measure two different scales; ABV (Zeiss) and % Mass w/w (Brix) on a single machine
  • 4 ½ digit LCD display
  • AISI 316 stainless steel sample dish – easy to clean, and offers rapid temperature stabilisation
  • Ultrasonically welded casing provide dust and moisture ingress protection to IP65
  • Touch of a button temperature display
  • Automatic temperature compensation means that your sample is analysed accurately regardless of its temperature
  • Water zero calibration – no need for expensive reference samples to calibrate
  • Provided with a certificate of calibration
  • Includes protective case & Certificate of Calibration
  • 12 month warranty
  • Dual scale: °Brix / °Zeiss
  • Automatic Temperature Compensation: Bx
