MA887 Digital Refractometer Salinity Meter

The MA887 salinity refractometer is an optical instrument that uses the refractive index to determine the salinity level in aqueous solutions. The method is simple and fast. Samples are measured after zero calibration with deionized or distilled water. In a matter of seconds, the instrument measures the refractive index of the sample and converts it to PSU, ppt, or SG units.
