  • 1. Coulometric titration method for total sulfur has the advantages of wide test range, high precision, good repeatability, high automation, safety and reliability, convenient operation for cleaning and changing electrolyte, and no need to change desiccant frequently.
    2. Automatic transmission of sample coding and weight information; backup and upload of test results; tamper proof of experimental data.
    3. Intelligent control of electrolytic switch can avoid over electrolysis due to misoperation. The integrated electrolytic cell is adopted without rubber plug to avoid air leakage.
    4. Input moisture value to automatically calculate and print dry basis sulfur content and moisture value
    5. Automatic judgment titration end point, shorten the experimental time, improve work efficiency.
    6. The latest 9999 historical records are stored and can be printed at any time.
    7. The working temperature of the system can be set between 600 ℃ and 1150 ℃ through the software (1050 ℃ for coal measurement and 800 ℃ for oil measurement).
    8. The microcomputer system adopts standard RS232 serial interface, which has the characteristics of simple connection, reliable transmission, long transmission distance and low failure rate.
    9. The microcomputer system is responsible for controlling the temperature of the high temperature furnace and collecting the measured data, and transmitting the data to the main control microcomputer through the serial line. The microcomputer processes the data and cooperates with the main program of the microcomputer to greatly improve the overall performance of the system.
    10. In this system, the high temperature furnace, magnetic stirrer, air purification device, electrolytic cell, automatic sample delivery mechanism and single-chip microcomputer control circuit are reasonably placed in the same box, which makes the whole system beautiful, small in size, convenient in placement and connection, and simple in operation and daily maintenance.
    11. Realize the login authority management; record the experiment process information.

  • Sulfur meter is the main instrument to measure the sulfur content in coal (microcoulometry is used to determine the sulfur content in petroleum). It is one of the important indexes to evaluate the quality of coal, and it is also one of the main components of air pollution. Therefore, the coal production departments and the departments of chemical fertilizer, power generation, civil use, coking and building materials all attach great importance to the analysis of total sulfur in coal. Sulfur detector is mainly used to determine the total sulfur content in coal, steel and various minerals. It is the preferred necessary instrument for laboratories of coal, electric power, chemical industry, building materials, metallurgy, geological exploration, commodity inspection, environmental protection testing and other departments.
