Gibitre MD Rheometer

Gibitre MD Rheometer measures the cure
characteristics of a rubber compound in conformity
ty with the international standards.
The measure of the vulcanization is carried out
by measuring the modification in the mechanical characteristics of the sample. The instrument permits to application of a cyclic strain to a test
piece and to measure the associated force. The
test is performed at a defined temperature and
the measure of stiffness is recorded continuously
as a function of time.
