This optical refractometer (brix meter) is equipped with a Brix scale in range from 0 - 20 °Bx (% mas sucrose). The measurement precision is ±0.1 °Bx.
It is suitable for measuring of fruits and vegetable (more precisely fruit and vegetable juices) and ripeness of the fruits (sugarcane, sugar beet, strawberries, melons, lemons, tomatoes, etc.). This refractometer could be also used for measuring of metalworking oil emulsions (content of oil or metalworking concentrate in water).
To determine the ripeness of the grapes we recommend model developed directly for viticulturists.
If you are a beer producer you can also measure the sugar content in wort (beer wort), but for you we have a special beer model.
| Scale range | Resolution |
| 0 to 20 °Bx |
0.1 °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 calculator for calculation of sugar content in aqueous solution

The measurement
The juice 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.
