Visual hand-held refractometers are classic, visual refractometers used for the determination of the refractive index of liquid media of low or high viscosity. They are mainly used for quick on-the-spot-control of process streams and the field analysis in fruit and vegetable plantations.

Applications / Determination of:
• % Brix (4 different measuring ranges available)
• % Oechsle
• Urine (0 – 12 g/dl)
• Salinity tests (0 – 28 %)
• Wine measurements (0 – 32 %Bx; 0 – 140°Oe)

Different models of hand-held refractometers for special applications and with different resolution and precision are available.
