Introduction: Your portable refractometer is a
precision optical instrument designed to measure
the concentration of salt in aqueous solutions. It
utilizes a salinity scale which is accurate and
easy to read. It is excellent for quality assurance,
process control requirements, and research.
Refractometers operate on the principle that as
the concentration or density of a solution increases, its refractive index changes proportionately. The refractive angle measured by your refractometer registers on the scale. The larger the
concentration of salt in solution, the higher the
reading on the scale.
