Index Rheometer of Ludwig, for measuring blood pressure. 1900 C. Hunt in C. E. Groves & W. Thorp Chem. Technol. III. 272 The rheometer is from its size adapted alike for indoor and street lighting. It is in reality a governor of volume, because..its action is independent of the size of the burner. 1930 Lancet 25 Oct. 910/2 A description of the technique of the method and the rheometer and photometer which are necessary for the purpose of the test. 3. Medicine. A syringe which uses a spring to withdraw a precise amount of fluid automatically, chiefly used in the delivery of antigens for the treatment of brucellosis.

(U.S. Public Health Service) 34 2667 Incidental to this method, Vernes devised a rheometer (for measurement of a definite amount of serum). 1990 A. MacMillan in K. Nielsen & J. R. Duncan Animal Brucellosis viii. 177 Perform this procedure..taking care to rinse the rheometer syringe thoroughly between samples. 4. Physics. An instrument for measuring the rheological properties of a substance, esp. one for measuring the viscous stress in a liquid.
