This brinometer gives the percentage of saturation in mass of sodium chloride in brine (i.e. in a water and sodium chloride solution).
If you can read 100 % on your hydrometer, it means that the solution is saturated in salt and any added salt will not dissolve but will remain it its solid form.
Range: 0-100
Unit: % saturation of NaCl in mass
Division: 1%
Accuracy: ± 1%
Calibration Temperature: 15.6°C (60°F)
