A Stein Hall cup for measuring the viscosity of a starch adhesive is automated to provide viscosity measurement in real time using a PLC or other data gathering and control processor. Temperature of the adhesive is measured concurrently with viscosity and temperature signals are processed with the timed viscosity signal to provide a temperature compensated value of starch viscosity.
