7. The dust clean in the tube so as to improve measurement stable and precision.

8. Internal oxygen purification has advantages of analysis low content.

9. The main circuit over current and timeout protection. When the loop current exceeds desired point or burning time more than 60s, the system cut the main circuit by itself, and this system can avoid high-power devices overheating damage, eliminating security risks. When the status of over current disappears, the main circuit automatically resume normal.

10. The system of high-frequency combustion and infrared detection system adopt fiber connection, cutting off direct electrical connection between the two, avoiding the burning furnace or external circuit can produce interference by cable transfers to infrared monitoring system and improves the data stable.

3. The analysis process of dynamic data integration, sampling every 32 seconds time, A/D change the frequency 150Hz-200Hz and it improves the analysis of sensitivity and accuracy.

4. The signal is tracked and its adjusted by itself.

5. Linear table of linear data high, medium and low can be corrected.

6. The process of analysis displays all kinds of real-time data and carbon and sulfur release curve.

7. There are 20 analysis channels to choose (each carbon and sulfur channels), and they can be arbitrary collocation, the choose range is very wide.

8. There are 100 carbon and sulfur release curves (each 50), it is can be stored at any time, and can be complete with carbon release curve and sulfur release curve.

9. Linearization calibration technology in full range, there are single and multi-point calibration, it can be set up one, two, three and more Linear calibration equation, and it improves Linear calibration equation and the correction of analysis data.

10. It can be communicated with data center or reported in front of the furnace.

11. Any brand of computers can communicate with this system.

12. A variety of print output mode.

13. It can communicate with any brand of electronic balance.
