Fully automatic industrial analyzerFunctional features:

1. Equipped with an imported electronic balance of one ten thousandth, using thermogravimetric analysis, 19 samples are tested quickly, automatically, and continuously. The analysis results of the air dry basis moisture, ash content, and volatile matter of each sample are obtained every 20 minutes, and the calorific value, fixed carbon, and hydrogen content of the sample are automatically calculated. Fast speed and high online level, can be used to guide production.

2. Adopting a three temperature dual furnace integrated structure, it can work in parallel, shorten the experimental time, and the constant temperature zones of the furnace do not interfere with each other, ensuring more accurate testing of air dry basis moisture, ash content, and volatile matter.

3. Adopting innovative heating devices and insulation materials to ensure that the furnace body is not damaged for a long time, with fast heating, accurate temperature control, and low failure rate.

4. Equipped with advanced and reasonable vacuum and smoke exhaust devices, ensuring accurate test results and laboratory cleanliness.

5. The computer automatically completes weighing data collection, result calculation, report printing, storage, etc.

6. The test results of air dry basis moisture, ash content, and volatile matter all meet the national standard requirements.

7. The control card adopts precision reference source, low drift high-precision operational amplifier, 12 bit A/D conversion chip, and has functions such as cold end compensation and over temperature software and hardware protection.

8. Using advanced PCI technology to adapt to the new development of computer technology, it can be combined with other instruments to form a comprehensive testing instrument, achieving multi control of one machine.

9. The testing software fully supports the Windows platform, with better stability, and can be connected to electronic scales and networked for remote data sharing.

10. Highly automated: After placing the sample, simply click the mouse to automatically complete the test and print the results, with simple operation.

11. Accurate testing: After testing more than 20 types of standard coal samples, the results are accurate and correct. Compared with the national standard method, the testing accuracy meets the requirements.

12. High efficiency: Rapid method: Moisture, ash, and volatile matter of 19 samples ≤ 150min
