HZDL-8 Automatic Sulfur Determination Apparatus for Coal

The HZDL-8 Chinese Character Automatic Sulfur Determinator produced by our company is primarily 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, 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 new features including automatic control of the electrolysis switch and PID mode control of furnace current, among many other intelligent control functions. The microprocessor also performs various corrections and processing of test data, ensuring stable measurement results, good parallel samples, and accuracy and precision that exceed the requirements of the national standard GB/T214-1996. Additionally, it features a large-screen Chinese character display, a user-friendly interface, simple and easy-to-learn keyboard operation, a high degree of automated intelligent control, and a compact size, 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.
