Full Automatic Proximate Analyzer (TGA)

Thermal Gravimetric Analyzer

Application Area

It is applicable in the industry such as electrical power, coal, commerce inspection, environment protection, metallurgy, papermaking, petrochemical, earth probe and the research institute or quality inspecting organization to test the content of air-dry basis moisture, ash, and volatile constituent in the coal. The instrument can also automatically calculate caloric value and the content of fixed carbon and hydrogen in the samples.

  1. Integrated with high precision electronic scale. Using thermogravimetry. Quickly, automatically and continuously tests 19 samples in every experiment. The air-dry basis moisture, ash and volatile constituent can be tested out in 90 minute, while volatile matter be tested out within 7 minutes for 2 samples. Automatically calculate the Calorific Value, fixed carbon and hydrogen content of the sample.
  2. Adopting the advanced dual furnace configuration, moisture, ash and volatile constituent can be tested in different furnaces.
  3. Using the advanced heating element and heat preservation materials to ensure the furnace body in stable condition. Meanwhile, the temperature rise more quickly, temperature control will be more precise, and malfunction rate lower.
  4. With the advanced and appropriate dust suction and fume exhaust devices, the testing results will be more precise and the laboratory cleaner.
  5. Data collection, calculation, print, and restoration are automatically done by computer.
  6. Two methods, predictive mode and classic mode are selectable to test the air-dary basis moisture and ash. While the volatile testing follows the standard of GB and ISO.
  7. Adopting precise reference source, low temperature drift and high precision operational amplifier, and 12-Bit A/D conversion chip in the controlling card, the instrument has the functions of cold end compensation, over-temperature protection both in hardware and software.
  8. Adopting the advanced USB technology, one computer can control several instruments. And the synthesized instrument can be composed combined with other instruments.
  9. Completely support Windows systems; high stability; can link electronic scale and share data in long distance through network.
