It is and optical refractometer (brix meter + brine meter) equipped with two scales:

  • Brix scale - designed for measuring of sucrose aqueous solutions, sugar content in fruit and vegetable juices, metalworking fluids (oil or metalworking concentrate content in water) in the range from 0 to 32 °Bx and measurement precision is ±0.2 °Bx.
  • scale for measuring of water salinity in range from 0 to 28 % and the The scale resolution is 0.2 5. The saturation point is highlighted on a scale by an extended line - it is maximal amount of soluble salt. No other added salt will be dissolved in the solution, it remains as a solid crystal.

This refractometer is suitable for example for preparation of salt brines before meat grilling or for cheese production (e.g. Jadel, Mozzarella, Greek cheese Feta, Balkan cheese, Bulgarian cheese, bjalo sirene, white cheese, salad cheese, sheep cheese) and also for the observing of fruit mash during the fermentation process (spontaneous natural fermentation) before the distillation.

The sweetness of ripe fruit which is the best for alcoholic/ethanol fermentation should be between approx. from 20 to 30 °Bx (see below in the table The usual concentrations of selected substances).
If you want to measure the "strength" of your brandy after the distillation in distillery we recommend refractometer for measuring of ethanol volume percent.

To determine the ripeness of the grapes we recommend model developed directly for viticulturists.

This refractometer is equipped with automatic temperature compensation.

Scale Scale range Resolution
Scale Brix (sugar content) 0 to 32 °Bx 0.2 °Bx
Scale Salinity 0 to 28 % 0.2 %

Example 1: if you measure value 25 °Bx it means that in the 100 g of aqueous solution is dissolved 25 g of sucrose. In other words, in 100 g of aqueous sucrose solution is 25 g of sucrose and 75 g of water. That is why is sometimes used the percent sign (%) as a unit because the sucrose content is a sucrose percentage by weight.

Example 2: If there is dissolved 100 grams of salt in 1 kilogramme of aqueous solution, the salinity of this solution is 10 %.

Tip: use our calculator for calculation of sugar content in aqueous solution

Title °Bx   Title °Bx
Metalworking emulsions 0 to 7   Rowan fruit 14
Beer wort 0 to 20 Semi-plums 15 to 18
Tomato juice 3 to 6 Prunus domestica Durancie 15 to 22
Peach juice 6 to 12 Dairy beverages 16 to 21
Orange juice 6 to 13 Plum 18 to 22
Apricots 8 to 11 Common juniper - berries 30
Sour cherry 8 to 18 Sorbets 25 - 32
Pears 8 to 22 Fruit juice concentrates 42 to 68
Damson (Prunus domestica insititia) 9 to 14 Condensed milk 52 to 68
Mirabelle plum (Prunus domestica syriaca) 10 to 15 Vegetable oil 57 to 90
Cherry 10 to 18 Sugar syrup 58 to 80
Great yellow gentian (bitter root) - root 10 to 25 Maple syrup 66
Apple juice, carbonated soft drinks 10 to 22 Fruit preserve, Jam, Jelly, Marmalade 60 to 70

Water salinity

Fresh water < 0.5 ‰
Brackish water 0.5 to 30 ‰
Saline water 30 to 50 ‰
Brine > 50 ‰

Tip: for measuring of salt solutions of very low concentration use model designed for seawater

The measurement

The liquids measuring is very easy. Place a few drops of measured liquid onto the prism, press slightly the cover plate to eliminate possible bubbles as well as air and the light/blue boundary will show you the result value.
