Dynamical Mechanical Analyzer (DMA) allows the dynamical determination of the main mechanical parameters of a large class of materials (metallic, plastic, composite, foams, wires) at temperatures of up to 650°C as well as of the phase transitions and activation energy. DMA 242 combines ease of handling with the user-friendly Proteus® measurement and evaluation software. This makes it fast and easy to characterize the dynamic mechanical properties as a function of frequency, temperature and time. Its modular design along with a wide variety of sample holders and cooling systems allow the DMA 242 to handle a broad range of applications and samples.
