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
