Huicheng DTA-1250S Differential Thermal Analyzer High Frequency Ceramic Furnace Body K/E Sensor 12 Order Program Temperature Control Temperature range Room temperature to 1250 ℃

Instrument introduction

Differential thermal analysis is a technique that measures the temperature difference between substances and reference objects and the temperature relationship under the control of the program. The differential thermal analysis curve describes the relationship between the temperature (△T) between the sample and the reference object with temperature or time. In DTA testing, changes in sample temperature are caused by endothermic or exothermic effects of phase transitions or reactions. Such as: phase transition, melting, transformation of crystal structure, boiling, sublimation, evaporation, dehydrogenation reaction, fracture or decomposition reaction, oxidation or reduction reaction, destruction of crystal lattice structure and other chemical reactions.

Instrument use

Phase transition, melting, transformation of crystal structure, boiling, sublimation, evaporation, dehydrogenation reactions, fracture or decomposition reactions, oxidation or reduction reactions, destruction of lattice structures and other chemical reactions.
