TMA-101/TMA-301 Thermomechanical Analyzer (TMA)

A thermomechanical analyzer tma is a technology designed to gauge a material's deformation concerning temperature and time under controlled temperature conditions and non-vibrational loads. It primarily assesses parameters like the expansion coefficient and phase transition temperature of materials. This versatile tool finds extensive application across various industries, including plastics, rubber, films, fibers, coatings, ceramics, glass, metal materials, and composite materials.

Instrumental Characteristics of Thermomechanical Analyzer (TMA)

USB or serial communication interface for easy connection to laptops.

In the experiment, the user sets the heating rate and the software PID controls the linear heating.

Calibrate various indicators of the instrument with standard samples.

The measurement process is automatically completed, automatically plotted, and can also be manually corrected. The computer automatically calculates the glass transition temperature, phase transition, softening temperature, etc.

Instrument Parameters of TMA Thermomechanical Analysis

Temperature range	room temperature~950 ℃.
Heating rate	0.1 ℃/min~20 ℃/min (using dual closed-loop self-learning intelligent PID temperature control to control linear heating).
Temperature control	Two sets of temperature measuring thermocouples, one set of thermocouples displays the furnace temperature in real-time, and the other set of thermocouples displays the sample temperature during operation
Temperature control accuracy	± 0.1 ℃.
Sample holder	TMA-101:quartz holder
Sample holder	TMA-301:Al2O3
Range	± 1000 μm
Resolution	0.01 μm (shape variable resolution)
Sensitivity	0.01 μm
Sample range	height 0.3-25mm
Sample range	diameter ≤ 10mm.
Load range	0-3.5N (controllable)
Operating modes	expansion, contraction, bending, needle insertion, etc.
Test atmosphere	Using a mass flow controller, the two channels of stable and stable gas can automatically switch during the experimental process, with high accuracy, good repeatability, and fast response speed. Atmosphere: inert, oxidizing, reducing, static, dynamic, gas flow rate: 0-200mL/min. The mass flow controller is required to have self calibration function based on different gas densities.
The instrument automatically collects and processes data by computer, automatically records, stores, and prints expansion coefficient, linear expansion amount, linear variable percentage time curve, linear variable percentage temperature curve, data and table curve, etc.
