DTA-1550 Differential Thermal Analyzer Introduction: Differential thermal analyzer is a technology that measures the temperature difference and temperature relationship between a substance and a reference substance under program-controlled temperature. In the DTA test, the change in sample temperature is caused by the endothermic or exothermic effects of phase transition or reaction. Mainly measures physical and chemical changes related to heat, such as the melting point, melting heat, crystallization and crystallization heat, phase transition reaction heat, thermal stability (oxidation induction period), glass transition temperature, oxidation or reduction reactions, lattice structure destruction, and other chemical reactions of substances. characteristic: 1. The new fully enclosed advanced ceramic furnace body design structure greatly improves sensitivity and resolution, as well as better baseline stability. 2. Adopting imported platinum rhodium alloy sensors, which are more corrosion-resistant, anti-oxidation, and have high sensor sensitivity. 3. Adopting Cortex-M3 core ARM controller, the processing speed is faster and the temperature control is more precise. 4. Adopting USB bidirectional communication, fully realizing intelligent operation. 5. Adopt a 7-inch 24 bit full-color LCD touch screen to display the status and data of the instrument in real time. 6. Intelligent software design, instrument automatic drawing throughout the process, software can achieve various data processing, such as enthalpy calculation, glass transition temperature, oxidation induction period, melting point and crystallization of substances, etc. Technical parameters: Temperature range: Room temperature~1550 ℃ Range: 0 to ± 2000 μ V Heating rate: 0.1~80 ℃/min Temperature resolution: 0.01 ℃ Temperature repeatability: ± 0.1 ℃ DTA accuracy: 0.01 μ V Temperature control method: Heating up: Program control can adjust parameters as needed Constant temperature: Program controlled constant temperature time can be set arbitrarily Curve scan: Temperature rise scan Atmosphere control: automatic switching of instruments Gas flow rate: 0-200mL/min Gas pressure: 0.2MPa Display mode: 24 bit color 7-inch LCD touch screen display Data interface: Standard USB interface Parameter standard: equipped with standard substances, with one click calibration function, users can calibrate temperature and enthalpy by themselves Working power supply: AC 220V 50Hz or customized Power: 600W
