The Thermogravimetric/Differential Thermal Analysis (TG/DTA) system combines the flexibility of DTA with the proven capabilities of the TG measurement technology, providing propert information for a variety of samples in the temperature range from 25-1200 °C. The simulateneous TG/DTA system can be used for such aplications as oxidation, heat resistance, the amount of water, compositional analysis and the measurement of ash content in a sample. This system is also used to cover such needs as reaction rate and accelerated degrading test.
