1150C Dta Differential Thermal Analysis Equipment
Product description:
Differential thermal analysis is a technique for measuring the temperature difference and temperature relationship between a substance and a reference substance under a program-controlled temperature. The differential thermal analysis curve describes the relationship between the temperature of the sample and the reference (ΔT) as a function of temperature or time. In the DTA test, the change in sample temperature is caused by the endothermic or exothermic effect of the phase transition or reaction. Such as: phase transformation, melting, crystal structure transformation, boiling, sublimation, evaporation, dehydrogenation reaction, fracture or decomposition reaction, oxidation or reduction reaction, destruction of lattice structure and other chemical reactions.
