This portable salt refractometer works in ambient light with no battery or other power source. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. Commonly used to help identify or confirm the identity  of a sample, asses the purity of a sample, or determine the concentration of a solute in a solution. Portable refractometers can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, the reliability, precision, and optical performance will last forever. Certificate of Calibration is available for this refractometer. Contact us for more information.
