Technical features of infrared carbon, hydrogen and nitrogen analyzer:
1. Single or double-layer sampling trays can hold up to 36 samples at once. Sample weights are automatically recorded. (Standard single-layer tray included)
2. The self-sealing technology isolates the internal air circuit from the external environment, preventing moisture and air from entering.
3. The special airway design can measure the true instrument blank value.
4. The system automatically cools down and shuts down after testing, enabling unattended operation.
5. The infrared cell features linearization correction, low drift, and long-term durability, with accurate test results.
6. The combustion process can be automatically adjusted to accommodate coal samples that are difficult to burn completely.
7. Real-time monitoring of laboratory temperature and humidity; automatic alerts for results exceeding the limits.
8. Automatic transmission of sample codes and weight information; backup and upload of test results; tamper-proofing of experimental data.
9. Implement login permission management; record information of the experiment process.
10. Fast testing process. Sample addition can be repeated, and new samples can be inserted at any position, enabling immediate testing upon sample arrival.
11. High automation level: features automatic sample placement, experimental process control, data processing, result calculation, linear correction, and report printing. The system performs automated loop testing to achieve fully unmanned operation.
12. Easy maintenance. The system intelligently diagnoses airway faults and automatically detects leaks throughout the entire system, significantly reducing maintenance complexity.
13. Intelligent Energy-Saving Control. The system automatically cools down or maintains a constant temperature in the lower target range after testing or during prolonged standby, achieving energy efficiency while extending the service life of high-temperature equipment.
14. The experiment is convenient. The fixed combustion process and automatic adjustment are combined to ensure the accuracy of the test results and reduce the test cost as much as possible.
