General Information


Differential scanning calorimeter (DSC)


Department of Materials Science and Engineering, Room 3B-0-38, Mekelweg 2, Delft (building #34)

Key words:

Phase transformation kinetics

Main application:

A differential scanning calorimeter is used to heat or cool the material over a temperature range, while measurements of heat flow are made. The technique is mainly applied for heat transfer calculations, including process simulation.

Instrument specification
