  • Parameter
  • Adopt standard
  • 21 samples can be placed at one time, and the test efficiency is the highest.

    1. The test results are accurate, accurate and stable. Optimized system design ensures complete combustion of coal sample, complete SO electrolysis and complete current (charge) integration.

    2. The design of hardware integration signal circuit with high precision and low drift, and the timely integration of hardware by single chip computer in the electrolysis process completely overcome the shortcomings of data easily missing in software integration, complete integration, effectively guarantee the accuracy of measurement value;

    3. High temperature furnace is heated by silicon-carbon tube, temperature is measured by Pt-Rh-Pt thermocouple and controlled by computer.

    4. The two-bar sample feeding mechanism greatly improves the stability of sample feeding, and the unique lifting and pushing structure effectively avoids the failure of sample feeding and sample clamping.

    5. Widening and thicker platinum electrolytic electrode sheet (195 mm_) and indicator electrode sheet (77 mm_) increase their area by 30% and 4 times, respectively, compared with ordinary instruments. The contact surface is large, and the integral is more accurate and complete.

    6. High degree of automation, automatic heating, constant temperature, cooling; storage and processing of test data.

    7. After 21 samples are placed at one time, samples can be automatically sent, tested, sampled and discarded, and no one is on duty. Samples can be added or replaced at any time during the experiment.

    8. The system design fully considers the fatigue resistance of instruments (especially components under high temperature environment). The high temperature furnace adopts imported new materials, which has good insulation effect and long service life.

    9. The unique working model and device design minimize the water vapor flowing into the drying pipe, supplemented by a large capacity drying pipe, which effectively reduces the frequency of desiccant replacement, operator labor intensity and operation cost.

    10. Use stable maintenance-free air pump, no need to replace rubber bowl, long service life;

    11. The airtightness check is convenient, and the operator can automatically complete it with a gentle touch of his finger.

    12. New protection design for leakage corrosion of electrolytic cell to avoid abnormal leakage corrosion to instrument.

    13. Equipped with muffler, it is healthy and environmentally friendly.

  • The WDL-9000B microcomputer automatic sulfur analyzer adopts Coulometric titration principle and is suitable for the determination of total sulfur content in coal, coke, petroleum and solid biomass fuels and SO3 content in cement.
