ABSTRACT:
A measuring apparatus for conducting a method of testing an apparent viscosity of grease. In this apparatus, four capillary tubes are connected to a cylinder and these capillary tubes are selectively opened to atmosphere one after another by a switching mechanism. When a piston is pushed by pressure applied to hydraulic oil supplied to one chamber formed in the cylinder, the grease contained in the other chamber is pushed out through one of the capillary tubes and the pressure required for the push-out is detected by a sensor. This measurement is repeated with each of the capillary tubes.
