Polartronic H532 Polarimeter

  • Highest measuring precision
  • Measurement of the optical rotatory dispersion (ORD)
  • Up to 5 wavelengths
  • No calibration due to spectral lamps

The Polartronic H532 is a high precision, high resolution (0.0001°) polarimeter with up to 5 wavelengths and utilizes the same advanced software as the ATR Series of refractometers.

The Polartronic H532 features a large programmable display for data input such as sample identification numbers, statistical evaluation in the case of multiple measurements and user-defined protocols for output via a printer or PC, and is individually adjustable for each of the 10 available methods.

With the appropriate software (AQUISYS 2008), the polarimeters of the Polartonic H series meet all requirements according to 21 CFR Part 11.
