![]() ![]() Metrological institutes help to ensure that these measurements are performed at the highest levels of precision and reliability. Automatically determine kinematic viscosity of lubricating oils, used oils. The aforementioned quantities of mass, length and time are fundamental physical quantities, and the accurate measurement of these quantities is of great importance in many scientific, technological and industrial applications. OptiMVD is a mini viscometer and density meter. Since viscosity cannot be measured directly, viscometers are instead used to measure an experimental parameter that is related to viscosity in a known manner. ![]() Viscometers are instruments used to measure viscosity. This is done within the framework of organizations such as the International Bureau of Weights and Measures (BIPM), which is responsible for the international coordination of metrology. Viscosity is a material’s resistance to flow under an applied stress, expressed as shear stress divided by shear rate. The internationally accepted unit for time is the second, which is defined based on atomic clocks.Ĭlose cooperation and comparison of atomic clocks at the international level, as you mentioned, is critical to ensure accuracy and consistency of time standards worldwide. Atomic clocks are based on the property of atoms to change between different energy states and use this to measure time accurately. In fact, PTB operates atomic clocks to provide high-precision time standards. RheocalcT software makes possible automated control and collection of test data. AMETEK Brookfield’s DV2T Viscometer is enabled with powerful programming capabilities to perform fast and easy viscosity measurements. The Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig is the national metrology institute in Germany and is responsible for realizing and disseminating the units of physical quantities. For Immediate assistance, Call 1-50 (US ET) Monday - Friday from 8:00AM - 5:00PM. View a variety of viscometers or viscosity meters, including rotational and glass capillary viscometers for measuring a fluid’s viscosity or resistance to flow. It is widely used to determine the viscosity of various fluids such as grease, paint, plastics, food, medicine, cosmetics, and adhesives.National metrology institutes play a decisive role in the definition and dissemination of standards for physical quantities. ![]() The rotary viscometer is used to measure the viscous resistance and liquid dynamic viscosity of liquids. The existing rotary viscometers are mainly in the form of drum type, cone plate type and parallel plate type viscometer. Solid Digital Rotary Viscometer Viscosity Meter Tester 1-1×10 (5)mpas (1) 545.99 New NDJ-9S Digital Rotary Viscometer Viscosity 10 6 000 000 mpa.s USA 599.00 New Digital LCD Rotary Viscometer Viscosity Tester Meter Fluidimeter Ndj-8s 319.99 New Brookfield Thermocouple cable No DV-250Y IN USA 19. Since most of the polymers are processed under viscous flow conditions, for the determination of the viscosity of the polymer, mastering the behavior of the viscous flow state is very important in the polymer production process. A rotational viscometer can be used to determine the viscosity and flow behavior of a polymer liquid. It is widely used to determine the viscosity of various fluids such as grease, paint, plastics, food, medicine, cosmetics, and adhesives.Īs scientific development and industrial production increase, it becomes very important to determine the viscosity of a substance. The Digital Viscosity Meter is used to measure the viscous resistance and liquid dynamic viscosity of liquids.
