high force dma instrument

High force DMA+series

The new DMA+ series instruments are dynamic testing machines based on a innovative concept of one-piece high rigidity test frame.

They are dedicated to the accurate analysis of the viscoelastic properties of most advanced materials. 

The DMA+ high-rigidity one-piece test frame has been designed to offer the largest stiffness and frequency analysis ranges, along with first-class ergonomics.

DYNATEST software makes possible an extended variety of DMA tests, in order to follow up the dependence of the material viscoelastic properties to many parameters.

Using the full DMA Suite software, the testing capabilities can be enlarged to enhanced fatigue testing  with  MULTITEST, and additional ad-on dedicated to Heat Build-Up testing, or crack growth testing.
