Refractómetro Digital RD.6712 para Veterinaria Lupas de medición green/blue and white/neutral density filterRefractometers are used for the identification of substances and the measurement of concentration in fluids. Because the refractive index (RI) of a solution is proportional to the concentration of a substance, it allows us to measure the purity and concentration of a solution. Euromex optical digital refractometers are calibrated at 20 Celsius. Most refractometers are equipped with automatic temperature compensation (ATC).
