Web5 mei 2024 · 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. Thus, a rheometer can be considered as a special type of viscometer. Viscometers only measure under one flow condition. WebAdditionally, the lab has rheometer and stereomicroscope, for analysis of bionks and quick check on structures after printing, respectively.
