Capillary viscometry 毛细管粘度计

Capillary viscometry is the most accuratemethod for the determinationof the viscosity of liquids witha Newtonian flowing behaviour.The measurement as such consists ina time measurement. The time measured is that whicha specific quantity of liquid requires to pass througha capillary having a defined widthａnd length. Conventionally, this processis watched with the humaneye,ａnd the flow time is measured manually using a stop watch.

In the caseofthe UVS MD Viscosity Measuring Device, the liquid meniscus is captured on the measurement planes, either inanoptoelectronic mannerby means of light barriers, or else ona thermo-resistant basis by thermistors.

 毛细管粘度计

毛细管粘度计是用于液体的粘度与牛顿流动特性的确定*准确的方法。测量本身是由一个时间测量。测定的时间是毛细管的特定数量液体通过具有特定宽度和长度的毛细管。通常，这个过程被用人眼来观测，并用秒表手动测量流动时间。

在UVS MD自动粘度测量装置是用光电方式或者基于热敏电阻的热抗性来测量液体凹面。
