Category for Thermomechanical Analysis (TMA) equipment that precisely measures thermal expansion and contraction characteristics of materials. Using probe-type or laser-type measurement methods, it quantitatively evaluates linear expansion coefficients, softening points, and glass transition temperatures of metals, resins, ceramics, and other materials. This equipment is essential for material selection, quality control, and product design in manufacturing industries, and is utilized for thermal property evaluation of automotive parts, electronic components, and construction materials. Unlike DSC (Differential Scanning Calorimetry) or TGA (Thermogravimetric Analysis), it performs measurements specialized in dimensional changes.
