HQR-1/2/3/4 Differential Thermal Analyzer (DTA)

The differential thermal analyzer investigates the correlation between sample temperature and its diverse physical and chemical properties. Equipped with microcomputer capabilities, the DTA series differential calorimeter enables qualitative analysis of substances, encompassing identification, composition, thermal parameter determination, and purity assessment. It aids in discerning whether thermal effects arise from physical or chemical processes and delves into phenomena such as phase transition, decomposition, combination, resolution, solidification, crystallization, evaporation, and sublimation in substances.

Instrument Feature of Differential Thermal Analyzer (DTA)

  • 01
    1

    Furnace controlled automatic lifting, positioning accuracy, improved measurement repeatability.

  • 02
    2

    Atmosphere control system use the flow controller (MFC), steady flow of gas can automatically switches in the process of experiment, high precision, good repeatability, response speed. (can be customized resistance to all kinds of corrosive gas atmosphere control system).

  • 03
    3

    All measurement process automatically, automatic drawing.Special data processing (DTA peak area and heat enthalpy calculation, kinetic parameters calculation, data comparison, many algorithms calculate the activation energy and glass transition temperature and comparison method to measure specific heat, etc.).

  • 04
    4

    System to collect samples in the process, can be arbitrary moment screenshot, according to the size of the output signal automatic transformation range.

  • 05
