Thermo gravimetric/ Differential Thermal Analyzer (TG/DTA)
About Instrument and its applications-
The Thermo gravimetric/Differential Thermal Analyzer (TG/DTA) combine the flexibility of DTA with the proven capabilities of the TG measurement capabilities, providing thermal property information for a verity of samples. TG/DTA System can be used for such application as oxidation, heat resistance, amount of water, compositional analysis and measurement of ash contents in a sample. This system is also used to cover such need as reaction rate and accelerated degrading tests.
