Refractometer – Master-series


Simple, hand-held analogue refractometer useful for measuring the brix of sugar solutions, eg in beverages, sauces, fruit juices or honey. A good alternative choice when the water resistant feature is not a priority.


  • Measurement of the brix of sugar solutions in food and beverage industry – eg jam, syrup, condiments, drinks and grapes
  • NEW MODEL! Master-53S – milky samples, such as creamy sauces, yoghurt, mayonnaise and opaque liquids in industrial processing
  • NEW MODEL! Master-Agri – growers, farmers, pack-houses
  • NEW MODEL! Master-Honey/Bx – bee keepers, honey distributors


  • Visibility – efficient use of an analogue unit depends on how easily the measured value can be read. The quality optics ensure that the measurement scale is very bright for a clear view
  • Durability – water resistant, dust-resistant and drop resistant. The only replacement part is the daylight plate
  • Smooth, easy-to-clean design – helps prevent samples being trapped, which could result in contamination
  • Automatic Sample Distribution – spoon shaped tip makes applying the sample very easy
  • Automatic Temperature Compensation – results in improved accuracy
  • Standards – comply with HACCP, GMP, and GLP standards

Calibration can be done with a 10% sucrose solution, 20% sucrose solution or or 30% sucrose solution.

How to measure:

  1. Apply 2 – 3 drops of the sample onto the prism
  2. Close the daylight plate. View the scale through the eyepiece.
  3. Read the measurement value where the boundary line intersects the scale.


  • Master-T – metal refractometer, general use
  • Master-PT – plastic refractometer, better suited to salty and acidic samples
  • NEW! Master-53S – specially designed for milky / opaque samples that were previously difficult to view a clear boundary line
  • NEW! Master-Agri – optimised for measuring the brix of plant juices from leaves, stems and roots. Can be used to measure measure fruit juices
  • NEW! Master-Honey/Bx – dual scale, measure the water content and brix of honey
