Automatic Thermal Analyzer

The fully automatic secondary thermal desorption analyzer excels in both performance and differential thermal analysis. It offers high-precision weight measurement, a wide monitoring range, and the ability to measure very small samples. Furthermore, the fully automatic secondary thermal desorption analyzer can perform comparative analysis between samples and standard reference materials, providing information about the sample's chemical composition. In terms of thermal stability testing, the analyzer can also obtain sample mass changes and weight loss rates relative to temperature changes, allowing for the assessment of the sample's heat resistance.
