Used for determining the softening point of
bituminous materials for road construction,
according to Wilhelmi method.
The softening point is the temperature where a
layer of thermoplastic material has a deformation
given by a steel sphere weighting 13.9 g.
The apparatus comprises a ring divided in two
halves on a metal support frame, glass beaker,
steel ball 15 mm diameter.
Weight: 2 kg approx.
