Viscosity and viscoelasticity measuring instrument

The meter which can measure wide range viscosity and viscoelasticity is offered. A measuring instrument has a cam, a 従動 arm, a thin board spring, a plate fixed implement, and an attachment-and-detachment type plate assembly. A cam is a circular disk which has a spiral type slot and rotates. The cam follower on a 従動 arm is in a corkscrew shape slot, therefore a 従動 arm circles around the fixed end as a cam rotates. A spring is attached to the fixed end of a 従動 arm, and is on the same line as it, therefore a spring circles to a 従動 arm and a counter direction. An attachment-and-detachment type plate assembly has a lower plate and an upper plate with the association sample surface which arranges examination fluid. A lower plate is 填る in the lower jaw of the plate fixed implement attached to the base of a meter. An upper plate is 填る in the upper jaw of the plate fixed implement attached to the free end of a spring. Fluid is arranged on the bottom sample surface. A cam rotates, a 従動 arm is pushed up, a spring circles downward and the sample surface is made to push one another by this. A cam is reversed and a spring gives separating power to a plate by this. A plate measures the time concerning separation and changes into a viscous value.
