LBTWY-9100 High-Frequency Infrared Carbon-Sulfur Analyzer

Description

Product Introduction:

The infrared carbon–sulfur analyzer, when used in conjunction with a high-frequency induction combustion furnace, enables rapid and accurate determination of the mass fractions of carbon and sulfur in steel, iron, alloys, nonferrous metals, cement, ores, glass, and other materials. As a cutting-edge, integrated instrument that combines optics, mechanics, electronics, computer technology, and analytical techniques, it features a wide measurement range and highly accurate, reliable analytical results. Thanks to its advanced computer‑based design, the instrument achieves state‑of‑the‑art levels of intelligence, graphical and textual display, and data acquisition and processing, making it an ideal analytical tool for determining carbon and sulfur content across a broad array of industries.

Product Advantages

1. An infrared detector with low noise, high sensitivity, and high stability is employed.

2. The instrument features a fully modular design, enhancing its reliability.

3. Automatic online connection of the electronic balance.

4. The WINDOWS operating system features a fully bilingual Chinese–English interface, making it easy to operate and quick to learn.

5. The software is fully featured, offering more than forty functions, including file assistance, system monitoring, channel selection, mathematical and statistical analysis, result correction, breakpoint adjustment, and system diagnostics.

6. Dynamically display the various data during the analysis process, as well as the carbon and sulfur release curves.

7. The measurement has a wide linear range and is scalable.

8. The high-frequency circuit is designed rationally, and the furnace’s power is adjustable, making it suitable for analyzing samples of various materials.

9. The automatic burner‑cleaning device helps minimize the impact of dust on analytical results.

10. The furnace-head heating device ensures consistent sulfur conversion rates, thereby enhancing the stability of sulfur determination.

11. The measurement has a wide linear range and is scalable.
