The ATR-L is a digital, multiple wavelength spectral refractometer ideal for research and development. The refractometer is equipped with a Peltier thermostat and provides automatic dispersion measurement at 7 wavelengths over the full range of visible light
The measuring principle of the ATR-L is similar to DNA analysis giving unique fingerprint-like data for a particular product. Using this fingerprinting characterisation; high quality products like wine, perfumes, alcoholic beverages etc. can be easily identified along with possible forgeries.
