A device for ascertaining the corrosiveness of a plastic melt, including a housing having a cavity to be filled with plastic melt; a first electrode made of a first material and a second electrode made of a second material, the first electrode and the second electrode each having a contact surface toward the cavity, the standard potential of the first material being higher than that of the second material, and the first electrode and second electrode additionally being connectable to each other via a measuring element for determining an electric current and/or an electric voltage between the contact surfaces.

Device for ascertaining the corrosiveness of a plastic melt

A method and apparatus for thermally analyzing a sample of a material by detecting a heat flow between the sample and a heat source ( ) and ,evaluating a functional relation between the measured heat flow and an associated temperature is based on controlling the heating power of the heat source ( ) so as to cause the heat source to follow a temperature program (T ) as a function of time superposed with a stochastic variation (F ), (FIG. ).
