Glas-Col GKH Stirrer Control

The Glas-Col GKH (HST10D) is a geared model with a totally enclosed, 1/17 hp, permanent-magnet DC motor. Digital readout displays speed in rpm's and torque in kg-cm. Front panel switch toggles between speed and torque. Actual speeds are displayed and maintained by a synthetic tachogenerator. Viscosity measurement is easier thanks to a controller with a digital readout switch able between speed and torque. Data on shear stress, shear rate, velocity gradients, and viscosity is accumulated easily with external DC multi-volt signals.
