Eltra - Thermogravimetric Analyzer - TGA Thermostep

Product advantages

  • Measurement of up to 19 samples in one analysis
  • Sample weights of up to 5 g
  • Fast heating rates, accurate temperature control
  • High-performance, precise weighing cell
  • Automatic placing and lifting of crucible covers
  • Robust design allows for use in laboratories and production

Function principle

Operation of the TGA Thermostep is simple and convenient. The measurement process has to be defined once regarding the used temperatures, atmospheres and heating ranges. To start the analysis, a predefined process simply has to be chosen in the software and the sample has to be weighed into the crucible. All further steps are processed automatically. All data processing, control of the measurement process and calculating of the result is done by an external PC with Windows®-based software. The determination of moisture, volatile and ash content needs about 4 hours.
