Automatic Refractometer (Abbemat WRHT / Anton Paar)

The Abbemat WRHT refractometer is a Heavy Duty refractometer for measuring the refractive index. The refractive index of a pure material is a physical property, which can be used to identify and characterize a sample. The measuring principle is based on critical angle of total reflection measured by shadowline detection with 2048-element linear CCD array and digital data processing. The instrument is capable of handling samples in liquid or semi liquids state. The instrument is controlled by an external PC through AbbematPC software.
