ATR-L Refractometer

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.

  • High-precision refractometer
  • Automatic dispersion measurement
  • Seven wavelengths fixed
  • Automatic ABBE number measurement
  • Ideal for research and development
  • 0.3 ml sample volume
