The AR4 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. Dry substance content in % and the dispersion value nF-nC can be calculated.
Typical applications
The Abbe refractometers have a wide range of applications in the chemical, petro-, oil- and fat industries, in the 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:
