Fisher Scientific Salinity Refractometer for Measuring Salt Content

Fisher Scientific’s Salinity Refractometer is a portable refractometer with rubber coated hand grip and construction.


Refractometer is precision optical instrument that operates on the principle- as the concentration or density of a solution increases, its refractive index changes proportionately. The refractive angle measured by refractometer registers on the scale. The larger the concentration of solute in the solution, the higher the reading on the scale.

  • Rubber coated hand grip and construction insulates test solution from inaccuracies caused by user's body heat
  • Comes with covered eye piece and bright, clearly defined scale with large easy-to-read measurements
