ATC 0-50% Brix Salinity Refractometer

It is an ATC refractometer used to measure the water content of liquids. It, therefore, measures the refractive index of the liquid, which varies with moisture content. It provides a high-resolution Brix scale for the most common tasks and provides highly accurate readings with 0.10 Brix divisions. It is an optical instrument made of high-quality aluminum that can be used to measure the density or refractive index of liquids. It uses only ambient light so no batteries are required
