I.Overview

This product is suitable for electric power, coal, metallurgy, solid waste, hazardous waste treatment, ore powder, petrochemical, quality inspection, cement, papermaking, geological prospecting, scientific research, colleges and other industry departments to measure hazardous waste, coal, coke, petroleum, etc. The total sulfur content in combustibles meets the standard GB/T214-2007 "Determination Method of Total Sulfur in Coal" and meets the requirements of ASTM 1552-03 standard sulfur content.

II.Performance Characteristics 

1. Equipped with a 7-inch large color LCD display, the overall visual sense is better than that of ordinary screens, and the display pictures are colorful, and there is no color difference such as low resolution on the picture;

2. With two channeling ports, the whole test process is automatically completed by the computer control, and it can also be used without the computer

3. The operation buttons adopt automatic touch buttons, which make the operation easier, more flexible and more efficient;

4. The whole test process after sample loading can be unattended, which greatly improves the test efficiency. The measurement process is automatically carried out by program control, automatic continuous sample delivery, automatic control of the start and end of the test, automatic coulometric titration, automatic data processing and data storage, and data printing.

5. It has a voice broadcast function. During the whole experiment, every button will have a voice prompt; including sample injection, sample output, experiment end, etc.), there will be voice prompts;

6. The coulometric titration method for measuring total sulfur has a wide range of testing, high test accuracy, and good repeatability; it is highly automated, safe and reliable; it is easy to clean and replace the electrolyte without frequent replacement of the desiccant.

7. The sample code and weight information are automatically transmitted; the test results are backed up and uploaded; the experimental data is tamper-proof.

8. Intelligent control electrolysis switch, will not cause over electrolysis due to misoperation. Adopting an integrated electrolytic cell, no rubber plug is needed to avoid air leakage.

9. Enter the moisture value, it can automatically calculate and print the dry basis sulfur content and moisture value.

10. Automatically judge the end point of the titration, shorten the experiment time and improve the work efficiency.

11. Store the latest 9999 historical records, and can print the historical records at any time.

12. The operating temperature of the system can be selected and set between 600°C and 1150°C through the software (1050°C for coal measurement, 800°C for oil measurement).

13. The microcomputer system adopts a standard RS232 serial interface, which has the characteristics of simple wiring, reliable transmission, long transmission distance, and low failure rate.

14. The microcomputer system is responsible for controlling the temperature of the high-temperature furnace, collecting measurement data, and transmitting the data to the main control microcomputer through the serial line, and the microcomputer performs data processing. The cooperation with the main program of the microcomputer greatly improves the overall performance of the system. .

15. This system reasonably places the high-temperature furnace, magnetic stirrer, air purification device, electrolytic cell, automatic sample delivery mechanism, and single-chip control circuit in the same chassis, which makes the whole system beautiful, small in size, and convenient to place and connect the system , The operation and daily maintenance of the system are simple.
