Portable, Benchtop & Process Models
Refractive index is an important parameter used in determining the quality, quantity, purity or mixing ratio of a chemical substance. It is a common measurement used by a variety of industries – chemical, food & beverage, cosmetic, flavors and fragrances, pharmaceutical, metal working, petrochemical, education/research and environmental. Krüss manufactures a wide variety of Krüss refractometer models to suit your needs from digital to manual hand-held portable refractometers. Each group of chemical refractometer products are listed below. Click here to learn some refractometer cleaning tips.
Digital Refractometers:

DR 6000 Digital Refractometers
Key Features of the DR6000 Series Digital Refractometer
Abbe Refractometers:

Abbe Refractometers
Abbe chemical refractometers measure the refractive index based on the principle of the total reflection that occurs at the boundary between a prism and a sample. They are ideal for the measurement of the refractive index of solid samples such as glass, plastics, polymers as well as foils, pastes and viscous liquids. A.Krüss Optronic carries two Abbe benchtop refractometer models.

Handheld Refractometers
Handheld refractometers are barely larger than a flashlight and can be used just about anywhere. They are easy to use, very robust and require no batteries. The models will differ based on their application such as the determination of salt content (salinity), water content in honey, Brix, alcohol content, urine and serum specific gravity, Oechsle, antifreeze and battery acid.
