Features

1. Integrated with high precision electronic scale. Using thermogravimetry. Quickly, automatically and continuously tests 20 samples in every experiment. The air-dry basis moisture and ash can be tested out in 150 minutes, while Volatile Matter be tested out with 7 minutes a sample. Automatically tests the Calorific Value, fixed carbon and hydrogen content of the sample.

2. Adopting the advanced dual furnace configuration, moisture, ash, and volatile matter 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-dry basis moisture and ash. While the volatile testing follows the standard of ASTM.

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 PCI/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.
