SPS-Europe is proud to offer K-Patents technology to determine the concentration of dissolved solids. K-Patents process refractometers use the optical measurement of a solutions refractive Index. In-line concentration measurement can be used as a real-time predictive tool for the final concentration.
Cost reduction is possible by reducing the variation of mean average of the product concentration.
