21 samples can be placed at one time, and the test efficiency is high.
1. The test results are precise, accurate and stable. The optimized system design ensures complete combustion of coal sample, complete SO electrolysis and complete current (charge) integration.
2, high precision, low drift hardware integration signal circuit design, a single single-chip microcomputer in the electrolytic process timely hardware integration, completely overcome the software integration easy to miss data, integral is complete, effectively ensure the accuracy of the measured value;
3, high temperature furnace for silicon carbon tube heating, platinum rhodium-platinum thermocouple temperature measurement, computer temperature control
4, the double rod sample delivery mechanism greatly improves the stability of sample delivery, and the unique lift and push-type structure effectively avoids sample sending and sample blocking failures;
5, the width and thickness of the platinum electrolytic electrode sheet (195mm²) and the indicating electrode sheet (77mm²), compared with the ordinary instrument, the area is increased by 30% and 4 times, the contact surface is large, and the integration is more accurate and complete.
6, high degree of automation, automatic heating, constant temperature, cooling; Store and process test data.
7. After placing 21 samples at one time, automatic sample delivery, experiment, sample delivery and sample loss can be unattended, and samples can be added/replaced at any time during the experiment;
8, the system design fully considers the fatigue resistance of the instrument (especially the components in high temperature environment), the high temperature furnace uses imported new materials, good insulation effect, long service life;
9. Unique working model and device design make the water vapor flowing into the drying pipe smaller; The auxiliary large-capacity drying pipe effectively reduces the frequency of desiccant replacement, the labor intensity of the operator and the operating cost;
10, the use of stable performance of maintenance-free air pump, no need to replace the rubber bowl, long service life;
11, the air tightness inspection is convenient, the operator only needs to use a finger gently, can be automatically completed;
12, the new electrolytic pool leakage corrosion protection design, to avoid abnormal leakage caused by corrosion of the instrument;
13, equipped with noise reduction device, health, environmental protection.
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.
