☆☆☆☆☆ ( 0 rates ) 377
Price : Call

Code: #18953

Supplier: A.KRÜSS Optronic GmbH

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.

rightMORE INFORMATION

  • 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.

    • Measurement of liquid, viscous and solid samples, regardless of their turbidity, viscosity, transparency and absorption
    • Suitable for the measurement of foils and solids
    • Large measuring range of nD 1.3000-1.7200 and 0-95%Brix, scale manually adjustable
    • Reading the measured values via an eyepiece
    • Robust housing and easy handling
    • With thermostat connections that allow for the temperature control with an external thermostat
    • Temperature is displayed on LCD screen
