Refractometer Leica AR600 is a precision automatic bench-top sodium D-line refractometer with digital readout. It measures index of refraction at sodium D-line nD of liquid samples at a user-defined temperature T (nDT) to 5th decimal place. Typical applications are sample characterization (nD20), chemical identification, concentration measurements (sucrose level in a fruit juice), purity determination.
