This optical refractometer (brix meter) is equipped with a Brix scale in range from 0 to 32 °Bx. The measurement precision is ±0.2 °Bx. It is suitable especially for measuring of fruit or vegetable juices sweetness, you can also measure the sugar content in wort (but we have also a special model for brewers or home brewers). We recommend this refractometer also for measuring of metalworking fluids (oil or metalworking concentrate in water), dairy beverages quality, cow or horse colostrum (beastings, bisnings or first milk) quality etc.
This refractometer is possible to use for fruit distillation or for Cider (Cyder, Cidre, Sidr) production - especially for measuring of sweetness of fruit mash and for observing the mash during the fermentation process (spontaneous natural fermentation). 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 range | Resolution |
| 0 to 32 °Bx |
0.2 °Bx |
Example: 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.
Tip: use our special calculators - the estimation of ethanol yield from fruit juice, calculation of sugar content in aqueous solution

The measurement
The dairy beverages 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.
