Differential thermal analysis (DTA) is a technique for measuring the relationship between temperature difference and temperature between material and reference material under programmed temperature control. Differential thermal analysis (DTA) curve describes the relationship between temperature (T) and time. In DTA test, the change of sample temperature is caused by the endothermic or exothermic effect of phase transition or reaction. Such as: phase transformation, melting, crystalline structure transformation, boiling, sublimation, evaporation, dehydrogenation reaction, fracture or decomposition reaction, oxidation or reduction reaction, lattice structure destruction and other chemical reactions.

[Differential Thermal Analysis Heating Furnace]
★ The furnace is made of 1kW Fe-Cr-Al wire bidirectional winding, eliminating the effect of the magnetic field generated by the furnace wire on the test results of the sample, and has a long heating constant temperature zone.
[Differential Thermal Analysis Temperature Controller]
★ Using the regulator to control the input voltage of the furnace wire, the heating process is heated up or cooled at a certain rate, and the temperature is constant.
三、Main features:
★ The instrument master chip uses the Cortex-M3 kernel ARM controller, which has a faster processing speed and more accurate temperature control.
★ Using USB two-way communication, the operation is more convenient.
★ With a 7-inch 24-bit color full-color LCD touch screen, the interface is more friendly.
★ The nickel Chromium alloy sensor is used to resist high temperature, corrosion resistance, and oxidation resistance.
