DTA-Differential-Thermal-Analyzer-QualiDTA-200.pdf

The QualiDTA Differential Thermal Analyzer provides high-precision measurement of temperature differences between a sample and a reference material, delivering critical insights into thermal behavior under controlled heating or cooling conditions. This advanced differential thermal analysis equipment enables the analysis of both endothermic and exothermic reactions, helping researchers gain a deeper understanding of material properties.

The DTA curve generated by the analyzer displays ΔT (temperature difference) as a function of temperature or time, making it possible to observe phase transitions such as melting, boiling, and crystallization, as well as chemical reactions like oxidation, reduction, and decomposition.

The QualiDTA-200 is a state-of-the-art Differential Thermal Analyzer
(DTA) designed to precisely measure the temperature difference
between a sample and a reference material under controlled
temperature conditions. The resulting DTA curve illustrates the
temperature difference (ΔT) as a function of temperature or time,
providing critical insights into various thermal properties and behaviors
of the sample.
In DTA experiments conducted with the QualiDTA-200, temperature
changes in the sample occur due to endothermic or exothermic
processes associated with phase transitions or reactions. These
processes include phase transformation, melting, crystal structure
transformation, boiling, sublimation, evaporation, dehydrogenation
reactions, fracture or decomposition reactions, oxidation or reduction
reactions, lattice structure destruction, and various other chemical
reactions.
The QualiDTA-200 is essential for researchers and engineers seeking
accurate thermal analysis for materials characterization, quality control,
and process optimization.
