Viscosity is the measurement of an ink or coating's actual performance on the press. It is the measurement of a fluid's internal friction, or its resistance to flow, under varying degrees of stress, stress rates and temperatures. A change of viscosity indicates variations in pigment concentration or percentages of solids, and can show the degree of polymerization of UV-cured ink or coating.
Viscosity measurement is the most sensitive control method of printing variables which affect the quality of your finished product, and is a determining factor in final print consistency.
The MINI DIGITAL REFRACTOMETER
is a precise, fast and easy way to determine % Brix concentration measurements of various liquid products. This unit features large, easy to read LCD displays in Brix (%) and Refractive Index (nD) and an automatic temperature compensation. It measures from 0 to 45% Brix with 0.1% resolution and 0.1% accuracy nD from 1.3330 to 1.4098.
