HW2000B High-Frequency Infrared Carbon and Sulfur Analyzer

I. Instrument Overview

The HW2000B High-Frequency Infrared Carbon and Sulfur Analyzer can quickly and accurately determine the mass fractions of carbon and sulfur in steel and its alloys, casting core sand, non-ferrous metals, rare earth metals, carbides, cement, ores, coke, catalysts, glass, ceramics, and other metallic and non-metallic materials. This instrument uses a high-frequency induction heating furnace to combust samples and employs infrared absorption methods for accurate carbon and sulfur content testing. This equipment incorporates advanced foreign technology, integrating optics, mechanics, electronics, computer science, and analytical techniques into a new technological product. It features a wide measurement range, strong anti-interference capability, comprehensive functions, simple operation, and accurate and reliable analysis results.
