    1, the use of vertical integrated structure, the automatic sample, sample mechanism, high temperature cracking furnace, electrolytic tank, agitator, air purification system and other components are cleverly combined together, so that the instrument structure is more compact, more reasonable, more stable.
    2, the instrument can be connected to the external electronic balance, by weighing the sample when the button can achieve automatic weighing. It can be loaded with 24 samples at a time, and has the queue-jumping function and re-queuing function, and the additional samples can get the opportunity to be determined in advance. Special flat bottom corundum porcelain boat is used to reduce the possibility of sticking. It is controlled by the program to realize automatic heating, temperature control, sample delivery, determination, and automatic saving and printing of the results. And the sample can be added in the middle, which greatly improves the work efficiency and truly realizes unattended.
    3. The whole test process after loading can be unattended, which greatly improves the test efficiency. The measurement process is automatically controlled by the program: automatic continuous sample delivery, automatic control of the start and end of the test, automatic coulometric titration, automatic data processing and data saving, data printing. In addition, the instrument has networking function, which can realize remote data sharing and remote upload of data reports.
    4, Coulometric titration electrolytic current using constant current scheme, by the software to achieve coulometric integration, so as to ensure titration results. The determination time can be automatically determined according to different coal samples, and each sample is about 5min. The speed is better than Eska gravimetry and high temperature combustion neutralization method.
    5, the system error can be directly through the software to achieve its own dynamic multi-point correction function, but also to ensure the test accuracy and accuracy of high, middle and low samples. The test results are better than the national standard, with good repeatability and high accuracy.
    6, the furnace adopts imported new energy-saving materials, good thermal insulation performance, fast heating speed, environmental protection, low carbon energy saving and high efficiency. PID temperature control precision is high, effectively protect the service life of the furnace and silicon carbon tube. In addition, the air intake function of the sample is increased, so that the sample can be completely burned quickly to ensure the test accuracy.
    7, the gas path adopts a new structure, the replacement of silicone loading and unloading drying pipe is very convenient and practical, and the air tightness is good, the failure rate is low. Adopt imported air pump to ensure stable and reliable air supply.
    8, the whole instrument structure adopts the modular design of components, component modules are easy to disassemble and interchangeable, which is very convenient for the installation, debugging and maintenance of the instrument and subsequent after-sales service. The automatic continuous sample sending mechanism is also used as a component, which can be exchanged between batches and stations, which is very convenient and completely solves the worries of users.
    9, the system design has a special fault diagnosis and detection program. At work, real-time monitoring of the functional components of the instrument, with fault judgment alarm prompt function. In addition, it also has a powerful debugging menu, which greatly facilitates the on-site installation and debugging of the instrument and the diagnosis and elimination of faults. Remote diagnosis and technical support can also be achieved through the Internet.
    10, the use of PID(proportional, differential, integral) temperature control algorithm, accurate temperature control, fast warming speed.
    11, the use of contactless switch, with broken pair protection, hardware overtemperature protection and electrolyte backflow prevention measures, safe and reliable use.
    12. Innovative multi-point dynamic coefficient correction method is adopted to ensure higher accuracy of test results for coal with high, medium and low sulfur content.
    13, the use of advanced USB technology, plug and play, reduce the requirements of the computer, can be controlled by a microcomputer multiple sulfur meter or with other instruments to form a comprehensive tester, experiment one machine multi-control.
    14, can be connected to electronic balance, can be networked to achieve remote data sharing.

  • 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.
