产品描述The rotational viscometer RVB-2 Series is a highly sensitive and reliable instrument used to measure and test the viscosity of a fluid. The motor is used to drive and regulate the constant speed of the rotor. When rotated the liquid will produce a viscosity moment. The higher the viscosity of liquids, the higher the viscosity moment and the lower the viscosity of liquids, the lower the viscosity moment. The viscosity moment is determined by the resistance to the sensor rotation, and the viscosity of measured liquids is calculated and displayed by the processor. The RVB-2 is used to determine viscosities of greases, paints, plastics, foods, pharmaceuticals, adhesives, and various other fluids.
