DTA Differential Thermal Scanning Analyzer Differential Thermal Analysis GA-1909

DTA Differential Thermal Scanning Analyzer GA-1909

Product Introduction:  

Differential thermal analysis (DTA) is a technique to measure the temperature difference and temperature relationship between a substance and its reference substance under programmed temperature control. The dTA curve describes the temperature (△T) between the sample and the reference as a function of temperature or time. In DTA tests, sample temperature changes are caused by endothermic or exothermic effects of phase transitions or reactions. Such as: phase transformation, melting, crystal structure transformation, boiling, sublimation, evaporation, dehydrogenation, fracture or decomposition reactions, oxidation or reduction reactions, lattice structure destruction and other chemical reactions.

Instrument features:

1. The main control chip of the instrument adopts Cortex-M3 core ARM controller, with faster processing speed and better temperature control.

2. USB two-way communication, more convenient operation.

3. Adopt 7 inch 24bit full-color LCD touch screen, more friendly interface.

4. Platinum rhodium alloy sensor, more high temperature resistance, corrosion resistance, oxidation resistance.
