Vicat/HDT Softening Temperature

Operator: Always included

Measuring of the heat deflection temperature by penetration of a needle (Vicat) or by bending (HDT)


With the HV3S HDT/Vicat tester, three samples can be measured simultaneously. According to the ISO norm, the heating rate is 50 or 120 °C/hour, but can be altered if required. A binary set of weights is available for each measuring station to ensure that the correct weight can be applied. Zero deformation is automatically set at the start of the experiment.
