粘度计
...方法可分为两类:一是绝对粘度;一是相对粘度。绝对粘度是由基本单位导出而得的,通常采用仪器为绝对粘度单位粘度计(viscometer),如同轴旋转粘度计、滑板式微膜粘度计等。
黏度计
黏度计(Viscometers):p:p Brookfield实验室黏度计有分为三种基本样式:模拟指针式、数字式以及可程控式。这三种主要明显的差异是在其黏度读数的显示。

振动式粘度计
A viscometer (also called viscosimeter) is an instrument used to measure the viscosity of a fluid. For liquids with viscosities which vary with flow conditions, an instrument called a rheometer is used. Viscometers only measure under one flow condition.In general, either the fluid remains stationary and an object moves through it, or the object is stationary and the fluid moves past it. The drag caused by relative motion of the fluid and a surface is a measure of the viscosity. The flow conditions must have a sufficiently small value of Reynolds number for there to be laminar flow.At 20.00 degrees Celsius the viscosity of water is 1.002 mPa·s and its kinematic viscosity (ratio of viscosity to density) is 1.0038 mm2/s. These values are used for calibrating certain types of viscometers.
