HT-CHN5000 Carbon Hydrogen and Nitrogen Element Analyzer is suitable for testing the content of carbon, hydrogen, and nitrogen elements in combustible materials such as coal, coke, and biomass fuels. It is widely applicable in industries such as power, coal, metallurgy, chemical, building materials, testing, geology, and research institutions.

Performance Features:

• High Efficiency: Equipped with a pneumatic sample tray, it allows continuous sample feeding and can hold up to 36 samples at once.
• Fast Testing Process: Supports cyclic sample addition and allows new samples to be inserted at any position, enabling immediate testing upon sample arrival.
• Compact and Aesthetic: The smallest and lightest element analyzer in its class.
• High Automation: Features automatic sample dropping, automatic control of the experimental process, automatic data processing, result calculation, and report printing, enabling unattended operation.
• Easy Maintenance: Automatic gas path fault diagnosis and leak detection, reducing the difficulty of instrument maintenance.
• Intelligent Energy Saving: Automatically cools down after testing or when idle for too long, maintaining a low target temperature to save energy and extend the lifespan of high-temperature components.
• Convenient Testing: Combines fixed combustion processes with automatic adjustments to ensure accurate test results while minimizing user testing costs.
• Long Service Life: High-stability infrared cell with complete independent intellectual property rights, featuring low drift, high efficiency, and durability.
• Remote Monitoring: The instrument can be connected to a laboratory management system via a network interface, enabling automatic data upload and full-process monitoring of testing.
