Page 17: Viscosity Measurement Function
점도 측정 기능 Viscosity Measurement Function 1. This instrument is not a viscosity measuring instrument that guarantees the value in measuring viscosity, and it is realized that it is possible to measure viscosity while stirring. This significantly reduces sample waste and experimental time with high reproducibility compared to the existing method, which requires the measurement of viscosity and stirring of the sample as separate experiments. - Page 18 ² Precautions when measuring viscosity : Samples that are difficult to measure with conventional viscometers can be equally difficult or difficult to measure with a viscometer stirrer. Please refer to the other precautions to be taken when measuring viscosity with this equipment. 1.
