Abbe refractometers are easy to use and only a small sample volume is required. They are well suited for all kinds of samples, no matter if solid, viscous or fluid. Transparency does not affect measurement. Refractive index (nD), dispersion (nf-nC) and concentration (%Brix) can be measured. For better accuracy prisms can be tempered and a digital thermometer is included in delivery.
