The PerkinElmer TMA 4000 is a uniquely designed thermomechanical analyzer (TMA) designed for optimal performance in measuring the coefficient of thermal expansion (CTE) in materials. This rugged and easy-to-use design uses both electronics and a unique Archimedean float system to control the probe, allowing accurate determination of CTE and of transitions. In these times of budgetary constraints and changes in material requirements driven by regulations like RoHS, understanding how a material changes with temperature is more important than ever. Test methods for TMA are now required for many industries and the TMA 4000 gives you a tool designed to collect this data. Data can be collected from samples in many forms with the TMA 4000's range of probes including expansion, compression, flexure, extension, and volumetric (dilatometry).
