Abstract
A rheometer according to an embodiment includes a substrate on which an object to be measured is placed, a vibration unit configured to provide a vibration to the substrate, a plurality of probe units each including a quartz tuning fork and a contact member fixed to the quartz tuning fork, the contact member being able to contact the object, the plurality of probe units having different types of the contact members. Any one of the plurality of probe units is selected and contacts the object, and a controller configured to calculate a viscoelastic force of the object based on a vibration of the vibration unit and a vibration transmitted to the quartz tuning fork through the object from the vibration of the vibration unit.
