Thermal mechanical analysis TMA measures the changes in sample size over time, temperature, and applied force in a controlled environment. TMA can measure the coefficient of thermal expansion (CTE) and other transformations such as glass transition (Tg). It can provide information on the compatibility of materials, their suitability for special environments, and their mechanical or physical properties.

TA Instruments cordially invites you to experience the world's best thermomechanical analyzers: Discovery TMA 450 and TMA 450 EM. With the excellent design you rely on and the expected innovation, the TMA Discovery series will meet your needs and exceed your expectations. Non contact, frictionless motors and high-resolution measurement sensors with a large range can provide the highest quality thermomechanical data required for the most challenging applications.

The Discovery 450 is equipped with a set of low expansion quartz probes designed to measure a range of sample configurations from solids to films or fibers. The Discovery TMA series can provide accurate and reliable data results for researchers who require simple thermomechanical data, researchers who require more complex options such as temperature modulation or dynamic force capability equipped with 450 EM, and researchers seeking optimal thermal mechanism data under humidification conditions.
