Thermo-mechanical Analysis (TMA) measures changes in the dimensions of a sample as a function of time, temperature, and force in a controlled atmosphere. TMA can measure Coefficient of Thermal Expansion (CTE), along with transitions such as the glass transition (Tg). It can provide information on the compatibility of materials, suitability of materials for special environments, mechanical properties, or physical characteristics of materials.
TA Instruments | Waters invites you to experience the world’s finest line of Thermomechanical Analyzers: The Discovery TMA 450 and TMA 450 EM. With the engineering excellence you depend upon combined with the innovation you expect, the Discovery line of TMAs will meet your needs and exceed your expectations. A non-contact, friction-free force motor and a wide-range, high-resolution measurement transducer provides the highest quality thermomechanical data required of the most challenging applications.
Featuring a set of low expansion quartz probes, the Discovery 450 is designed to measure an array of sample configurations from solids to films or fibers. For those researchers requiring straightforward thermomechanical data, to those demanding more sophisticated options such as temperature modulated or dynamic force capabilities (available in the 450 EM), to those looking for the best thermomechanical data under humidified conditions, the Discovery TMA series delivers accurate, reliable results.
