The HI96811 Digital Refractometer converts the refractive index of a juice or must sample to % Brix. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in the refractive index with temperature for a percent by weight sucrose solution. Since the majority of sugar in grape juice and must is fructose and glucose instead of sucrose, the reading is sometimes referred to as “Apparent Brix”. Typical grapes at harvest will be between 19-24% Brix or degrees Brix (°Bx). The HI96811 is an easy-to-use tool for winemakers for measuring sugar in grapes or must, in the field or in the lab.

  • Designed for winemaking sugar analysis
  • Temperature Compensation algorithms based on sucrose solution
  • 0 to 50% Brix range with an accuracy of +/- 0.2% Brix


Features, at a glance:

  • One-point calibration - Calibrate with distilled or deionized water
  • Small sample size - Sample size can be as small as 2 metric drops (100 μl)
  • Quick, accurate results - Readings are displayed in approximately 1.5 seconds
  • Dual-level LCD - The dual-level LCD displays % Brix and temperature readings simultaneously
  • Battery indicators - Battery percent level remaining at startup and low battery indicator
  • Automatic shut-off - To conserve battery life the meter shuts off automatically after three minutes of non-use
  • Stainless steel sample well - Easy to clean and corrosion-resistant
  • IP65 water-resistant protection - Water resistant ABS plastic casing designed to perform under laboratory and field conditions.
  • Automatic Temperature Compensation (ATC) - Samples automatically compensated for temperature variations
  • 1 button calibration, only requires 2 metric drops of sample (100 μl), fast 1.5 second response time for temperature compensated readings
  • IP65 Water Resistant Protection with ABS plastic casing for both lab and field conditions
  • LCD display displays both %Brix and temperature simultaneously, automatic shut off after 3 min of non use to preserve battery life
