A rheometer apparatus and methods of use are provided. In one embodiment, the rheometer includes a sleeve having an interior space; a cylindrical bob disposed within the interior space of the sleeve and coupled to a first end of a bob shaft; a cross-spring pivot coupled to a second end of the bob shaft; an arm coupled to and projecting radially from the cylindrical bob; and a linear actuator coupled to the arm. In some embodiments, the rheometer apparatus may facilitate more accurate gel shear strength measurements and/or may be correlated with existing rheometer measurements.
