Abstract:

An apparatus is disclosed for determining the viscosity of fluids a nd for determining the point of gelation during the curing of a material. Attached to one end of an oscillating lever, a disposable probe is immersed in a small fluid specimen, while a strain gauge and a displacement transducer are attached to the lever for monitoring its movement. The viscosity of fluids is correlated with the strain measurement, while the gelation point of a material during its curing cycle is determined by monitoring the phase angle between the strain gauge output and the lever displacement transducer output.
