Abstract
A portable viscometer includes an instrument body having an electrical control circuit disposed therein and sensor probe for immersion into a fluid to be analyzed. The sensing probe includes a crystal resonator-type sensor and a temperature sensor that provide sensing signals to the electrical control circuit indicative of fluid viscosity. The resultant viscosity is displayed and/or stored.
