Measure the viscosity of fluids with viscometers from Grainger. Automatic viscometers are specifically developed for industrial users in non-laboratory environments. They can measure the kinematic viscosity of engine, gear, and industrial lubricants at either 40 or 100 degrees C. Digital paddle viscometers accurately measure the viscosity of emulsified asphalts, suspensions, marine fuels, residual oils, slurries, paints and similar materials.
