DMA: Dynamic Mechanical Analysis

TA Instruments 2920 Modulated DMA

The Q800 is the world’s best-selling DMA, for very good reasons. It utilizes state-of-the-art, non contact, linear drive technology to provide precise control of stress, and air bearings for low friction support. Strain is measured using optical encoder technology that provides unmatched sensitivity and resolution. With its unique design, the Q800 easily outperforms competitive instruments, and is ideal for high-stiffness applications including composites

  • Magnetic drive motor for precise stress control over a wide force range
  • Unique low friction are bearing design for enhanced sensitivity for measuring weak samples
  • Automatic movement for opening and closing furnace for precise temperature control over the entire temperature range
