VISCOSITY TESTING PORTABLE

To learn more about viscometer applications and the importance of fluid behavior, please watch the video and read the informative brochures provided below. Whether in use in the laboratory or on the production floor, PCE Instruments' easy-to-use viscometer devices provide accurate, reliable viscosity measurements. 1 millipascal-second (mPa.s) = 1 centipoise (cP)

Nature of your fluid (Newtonian, non-Newtonian, dilatant, thixotropic, etc.) Required rotational speeds or shear rates Viscosity range of your fluid (low, medium or high) To determine the right viscometer for your application, consider the following factors: Benchtop or stationary viscometer devices are complex rheological measuring systems that allow for a more detailed examination of liquid samples.

VISCOSITY TESTING PORTABLE

Handheld or portable viscosity meter devices allow users to take simple, single-point measurements in the field and in the lab. PCE Instruments offers a variety of handheld, portable, benchtop and in-process, real-time viscometer products that measure the absolute / dynamic (shear) and kinematic viscosity of fluids. Companies can save money by placing a viscometer in a production line and making fluid viscosity measurements in real time. A viscometer can be an important component in process and quality control. The technical term to refer to this is extensional viscosity.Ī viscometer is frequently used in laboratories, but it also has practical applications in factories and other industrial environments.

However, a fluid's viscosity also may be measured on the basis of stretching. Rotational viscometers with rotating spindles or rotors, also known as 'cup and bob' or Searle viscometers, are the most common tools used to measure the shear viscosity of fluids. The term viscosity typically refers to shear viscosity, i.e., how a material reacts to being sheared. This correlation may be useful for anticipating the need for repeat plasmapheresis.A viscometer, viscosity meter or rheometer is a measuring instrument used to determine a fluid's internal flow resistance or viscosity. Serum viscosity and electrophoresis are recommended before and after plasmapheresis in order to correlate viscosity and M-spike with patient symptoms. Hyperviscosity syndrome can also occur in multiple myeloma patients.īecause the ability of a monoclonal protein to cause hyperviscosity is affected by its concentration, molecular weight, and aggregation, sera with concentrations of monoclonal IgM greater than 4 g/dL, IgA greater than 5 g/dL, or IgG greater than 6 g/dL should be tested for hyperviscosity. The most common cause of serum hyperviscosity is the presence of large concentrations of IgM monoclonal proteins, and Waldenstrom macroglobulinemia accounts for 80% to 90% of hyperviscosity cases. Funduscopic examination reveals dilation of retinal veins and flame shaped retinal hemorrhages. Hyperviscosity may be manifested by nasal bleeding, blurred vision, headaches, dizziness, nystagmus, deafness, diplopia, ataxia, paresthesias, or congestive heart failure. Viscosity is the property of fluids to resist flow.
