Introduction: This precision optical instrument

is designed to measure the concentration of salt

in aqueous solutions. It features automatic tem-

perature compensation (ATC) which makes man-

ual temperature correction unnecessary in a

range of 10 to 30°C. This refractometer utilizes a

parts per thousand (ppt) scale which is accurate

and easy to read. 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.
