viscometer

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.06 sec.

viscometer

Instrument for measuring the viscosity (resistance to internal flow) of a fluid. In one type, the time taken for a given volume of fluid to flow through an opening is recorded. In the capillary-tube viscometer, the pressure needed to force the fluid to flow at a specified rate through a narrow tube is measured. Other types depend on measurements of the time taken for a sphere to fall through the fluid, or of the force needed to rotate the inner cylinder of a pair (the space between the two cylinders being filled with the fluid under test), or of the rate at which oscillations of a disk vibrating in the fluid die out.

U-Can Dynatex instrumentation sold by this company and featured in this one-page, four-color bulletin includes rheometers, Mooney viscometers, fatigue testers, flex-cracking testers, tire plunger testers, air permeability testers, aging ovens, constant temperature and humidity chambers, ozone test chambers, electronic densimeters, abrasion resistance testers, carbon black dispersion testers, electronic tensile testers, tire cutting machines and more.
An oscillating parallel-plate rheometer, the APA 2000 differs from a Mooney viscometer or a typical dynamic rotational rheometer in that it has two permanent (rather than disposable) parallel flat dies or plates oscillating against each other.
The R 180 viscometer is a portable, battery-operated instrument designed for rapid and accurate viscosity determination either as a stand-alone laboratory instrument or for use directly in the production environment.
