Abstract
A rheometer has temperature control means which include a bath through which liquid is circulated, so that it will completely immerse both the upper and lower probes or plates between which a sample, whose rheological are being investigated, is located. This allows the temperature of the sample to be closely controlled to within 0.2.degree. C. of a selected temperature. The rheometer is particularly suitable for measuring the properties of bitumous materials which are extremely temperature sensitive.
