Introduction: The high temperature differential thermal analyzer mainly for industrial users, scientific research and teaching, is widely applied in all kinds of material and product research and development, in the field of chemical process optimization and quality inspection quality control, etc.Main measuring heat related physical and chemical changes, such as melting, crystallization point crystallization hot melting point of material, phase change heat of reaction, thermal stability (oxidation induction period), the glass transition temperature, etc. Features 1, imported furnace for rapid heating of the sample. 2, atmosphere control system using mass flow controller, two lines of voltage regulator, steady flow gas can automatically switches in the process of experiment, high precision, good repeatability, fast response speed (can customize the resistance to all kinds of corrosive gas atmosphere control system). 3, the whole measurement process automatically, and automatic drawing, use of software function can complete DTA conventional data processing; 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.). 4, in the process of the system to collect sample, can be arbitrary moment screenshot, automatic transformation range. According to the volume of the output signal. 5, the user can use of indium, tin, lead and standard sample on the accuracy of the instrument of temperature, energy correction. 6., LCD display, real-time display of the instrument condition and data, two sets of temperature measuring thermocouple, a set of galvanic real-time display temperature (regardless of the heating furnace work or not) another set of galvanic couple sample temperature display work. 7, the user the calculation formula and calculation method, our factory can provide the corresponding software development products. 8, independent research and development of the constant temperature controller; Constant temperature gas chromatography and mass spectrometry connected head; Constant temperature; Can fully guarantee the tar and various kinds of secondary reaction gas detection. Technical Parameter LCD real-time display temperature and sample temperature, gas circuit state, etc Abscissa axis can choose temperature or time scale Glass transition temperature, specific heat measurement, Cooling curve function Crystallization kinetics DSC data DSC measurement range: plus or minus 1 mw ~ + 100 mw DSC precision: plus or minus 10 (including W Temperature data Temperature range HKR: at room temperature to 950 ℃ The heating rate: 0.1 ℃ / min to 300 ℃ / min After vacuum: equipped with vacuum unit can reach 2.66 x 10-2 pa Constant temperature range: 0-400 ℃ Differential thermal data Measuring range: plus or minus 10 μv to + 2000μ v Including DTA resolution: 0.01 v DTA noise: < 0.01 μv
