The AR2008 determines the refractive index between nD 1.3000–1.7200 and the sugar content in the range of 0–95 %Brix of liquid, viscous as well as solid samples. The dry substance content in % and the dispersion value nF-nC can be calculated. The output of the measurement results is performed digitally. The refractive index of the Brix value is shown on the LCD display together with the temperature.
Typical applications KRÜSS AR2008
The Abbe refractometers have a wide range of applications in the chemical, petro- and food industry, in hospitals, pharmacies and research offices, as well as in research and teaching. The special feature is the possibility to measure not only liquid and viscous samples but also solids and foils. Main application fields are:]
- Identity test, purity control and concentration determination of raw materials, semi-finished products and end products
- Determination of the sugar concentration
- Incoming and outgoing goods inspection
- Purity control
- Testing of food and pharmaceutical products
- Testing of the compliance with national and international standards
- Training
