Polartronic H532

The Polartronic H532 is a high performance circle polarimeter with up to 5 wavelengths. The system has the highest precision and resolution, ideal for applications dealing with different substances and requiring extreme accuracy; e.g. in pharmaceutical, medical and chemical laboratories. Spectral lamps make the system calibration free.

  • Highest measuring precision over the entire measuring range by direct measurement of the angle
  • Short measuring times, no mechanical wear
  • Determination of the optical rotatory dispersion (ORD), measurement at several wavelengths
  • Calibration free because of spectral lamps
  • 21 CFR part 11 software available
