2. Viscometer - Wikipedia

   en.wikipedia.org/wiki/Viscometer

   If a test with any geometries runs through a table of several shear rates or stresses, the data can be used to plot a flow curve, that is a graph of viscosity vs shear rate. If the above test is carried out slowly enough for the measured value (shear stress if rate is being controlled, or conversely) to reach a steady value at each step, the ...

3. Mini-rotary viscometer - Wikipedia

   en.wikipedia.org/wiki/Mini-rotary_viscometer

   The mini-rotary viscometer is a device used to measure the pumpability of an engine oil at low temperatures. [1] [2] Engine oils must meet viscometric standards including those determined by the MRV in order to be classifiable within SAE J300 viscosity grades.

4. Marsh funnel - Wikipedia

   en.wikipedia.org/wiki/Marsh_funnel

   Based on a method published in 1931 by H.N.Marsh, [1] a Marsh cone is a flow cone with an aspect ratio of 2:1 and a working volume of at least a litre. A Marsh funnel is a Marsh cone with a particular orifice and a working volume of 1.5 litres.

   Brookfield Engineering is an engineering and manufacturing company with headquarters in Middleboro, Massachusetts.It is a subsidiary of the conglomerate Ametek.Its product line includes laboratory viscometers, rheometers, texture analyzers, and powder flow testers as well as in-line process instrumentation.

6. Mooney viscometer - Wikipedia

   en.wikipedia.org/wiki/Mooney_viscometer

   A Mooney viscometer MV 2000 Mooney Viscometer. A Mooney viscometer or rotating disk viscometer is an instrument used for measuring the Mooney viscosity of rubbers. [1] Invented in the 1930s by Melvin Mooney, [2] it contains a rotating spindle and heated dies, the substance encloses and overflows the spindle and the mooney viscosity is calculated from the torque on the spindle.

7. Ubbelohde viscometer - Wikipedia

   en.wikipedia.org/wiki/Ubbelohde_viscometer

   [2] [3] It is recommended for higher viscosity cellulosic polymer solutions. The advantage of this instrument is that the values obtained are independent of the total volume. The device was developed by the German chemist Leo Ubbelohde (1877-1964). ASTM and other test methods are: ISO 3104, ISO 3105, ASTM D445, ASTM D446, ASTM D4020, IP 71, BS 188.
