Heat Deformation Tester

Heat Deformation - HDT/VSP Tester is a consistent tool useful for determining the ability of a given polymer to bear load at elevated temperatures. Accurate and reliable deflection or deformation is an important component in the plastics industry. PRESTO Heat Deformation HDT/VSP tester is equipped with indenter which indents the sample under specific load and offers heat deformation and Vicat Softening temperature of plastic or polymer materials. The deflection on the gauge is the measure of deformation of the test specimen.
