This optical refractometeris used for measuring of aqueous solution salinity in the range from 0 to 28 %. Sometimes it is called as "brine meter".
This refractometer is suitable for preparation of brines in bakery, salty cheese plants (e.g. Jadel, Mozzarella, Greek cheese Feta, Balkan cheese, Bulgarian cheese, bjalo sirene, white cheese, salad cheese, sheep cheese), meat brining before grilling, meat and vegetable pickling solutions or also for example for winter road maintenance.

Example: One kilogramme of water where is dissolved 100 grams of sodium chloride has a salinity of 10 %.
Water salinity
| Fresh water |
< 0.5 ‰ |
| Brackish water |
0.5 to 30 ‰ |
| Saline water |
30 to 50 ‰ |
| Brine |
> 50 ‰ |
Tip: for measuring of aqueous salt solution 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.
