  • Automatic viscosity measuring device
    Patent number: 5142899
    Abstract: An automatic viscosity measuring device which measures sample levels, automatically fills a sample to a marked line by vacuum pressure, automatically counts the time for the sample to fall by a sensor in the upper and lower marked lines, finds intrinsic viscosity by concentration and then measures the degree of error from relative viscosity in the case of the Ostwald's viscosimeter, which automatically measures the viscosity of a high molecular material.
