2.  It adopts imported alloy sensor, which is more corrosion-resistant, anti-oxidation and high sensitivity.

3.   With Cortex-M3 core arm controller, the operation speed is faster and the temperature control is more accurate.

4.  USB two-way communication is adopted to realize intelligent operation.

5.  The 7-inch 24-bit color full-color LCD touch screen is used to display the status and data of the instrument in real time.

6.  Intelligent software design, automatic drawing of the whole process of the instrument, software can realize various data processing, such as calculation of enthalpy, glass transition temperature, oxidation induction period, melting point and crystallization of substances, etc.

Instrument introduction:

Differential thermal analysis (DTA) is a technique to measure the relationship between temperature difference and temperature between substance and reference substance under the temperature controlled by program. In DTA test, the change of sample temperature is caused by phase transformation or endothermic or exothermic effect of reaction.

Instrument purpose:

It mainly measures physical and chemical changes related to heat, such as melting point, melting heat, crystallization and crystallization heat, phase change reaction heat, thermal stability (oxidation induction period), glass transition temperature, oxidation or reduction reaction, lattice structure damage and other chemical reactions.
