Unsalted soluble solids can be calculated by combining refractometer and salt meter. According to JAS method, unsalted soluble solids is calculated by subtracting titrated salinity from the Brix. ATAGO's salinity meter uses conductivity rather than the titration method, however, it is perfect to use on-site as a simplified method to compute unsalted soluble solid.
We also have another model PAL-SALT Mohr which gives a reading similar to those obtained from the Mohr's method (titration).
