The HZDL-8 Chinese Character Automatic Sulfur Determinator produced by our company is mainly used to measure the total sulfur content in coal, steel, and various minerals. It is the preferred instrument for laboratories in sectors such as coal, power, chemical industry, building materials, metallurgy, geological exploration, commodity inspection, and environmental protection testing.

This instrument is designed based on the coulometric titration method specified in GB/T214-1996 and has been improved and developed on the basis of the KZDL series and other existing domestic sulfur determinators. It addresses the shortcomings of the KZDL-3A model, such as poor linearity, zero drift, the need for manual control of the electrolysis switch, and manual adjustment of furnace current. The entire measurement process of this instrument is intelligently controlled by a microprocessor, with many new intelligent control functions added, such as automatic control of the electrolysis switch and PID mode control of furnace current. The microprocessor performs various corrections and processing on the test data, ensuring stable measurement data, good parallel samples, and accuracy and precision of results that exceed the requirements of the national standard GB/T214-1996. Additionally, it features large-screen Chinese character display, a user-friendly interface, simple and easy-to-learn keyboard operation, a high degree of automated intelligent control, compact size, and many other advantages, making it an ideal sulfur determinator for laboratories.

● Performance Characteristics of the HZDL-8 Chinese Character Automatic Sulfur Determinator: 

■ Controlled by an advanced single-chip microcomputer, it compensates for deviations caused by measurement conditions and offers high resolution. 

■ It uses a full Chinese LCD display, and the sample feeding mechanism employs electronic switches for higher reliability. 

■ It uses PID control for furnace current, automatically adjusting the furnace current size, which can extend the service life of silicon carbide tubes by three times compared to traditional controllers. 

■ It automatically determines the titration endpoint, automatically switches electrolysis on and off, and avoids over-electrolysis.
