HT-HW500 Automatic Infrared Sulfur Analyzer is suitable for analyzing and determining the mass fraction of sulfur in steel, non-ferrous metals, cement, ores, glass, ceramics, and other metallic or non-metallic materials. It is a commonly used analytical instrument in physical and chemical laboratories.

Features:

• Batch testing: Up to 24 samples can be loaded at once. The priority of samples can be dynamically adjusted during testing, and samples can be added, deleted, or inserted at any time. Supports cyclic loading.
• High automation: Automatic weighing, sample feeding, data processing, result calculation, report printing, etc., enabling unattended operation.
• Fast testing speed and accurate results: Equipped with a sample blowing function to ensure rapid and complete combustion of samples.
• High precision: Features unique multi-point dynamic calibration and optional primary, secondary, and tertiary calibration methods to ensure accuracy for samples with high, medium, or low sulfur content.
• High reliability: Utilizes internationally advanced key components to design a highly stable, low-drift infrared cell. Multiple hardware and software protections and self-diagnostic technologies ensure stable operation.
• Intelligent energy-saving control: Automatically cools down after testing or when idle for extended periods, maintaining a low target temperature to save energy and extend the lifespan of high-temperature components.
• Smooth operation: Employs a flexible transmission sample feeding mechanism, effectively resolving industry challenges such as excessive noise and crucible dropping during feeding.
• Strong adaptability: Simplified gas circuit connections for user convenience.
• Full-process monitoring: The instrument can be connected to a laboratory management system via a network interface for automatic data upload and comprehensive monitoring of the testing process.
