Contact formThe HTTNS-6000 Sulfur and Nitrogen Analyzer uses ultraviolet fluorescence and chemiluminescence methods to determine nitrogen content, which enhances its ability to resist impurity interference. It avoids the cumbersome operation of the titration cell in the coulometric method and the resulting unstable factors, thereby significantly improving the sensitivity of the instrument. The key components of the system adopt imported devices, ensuring reliable performance of the entire machine. Application fields: environmental protection, chemical industry, biological industry, petroleum, energy.
Features：
Based on the Windows Chinese operating interface, direct human-machine dialogue is available. The computer controls data collection, processing, storage and printing. The instrument automatically adjusts the gas flow without manual adjustment; the sampler is controlled by the computer; a new gas pressure abnormality alarm function is added.

HTTNS-6000Advantages of Sulfur and Nitrogen Analyzer
1. The ozone destroyer adopts the high-temperature destruction method.
2. Built-in electronic mass flow meter, the gas flow is automatically controlled by the operating software, the program automatically tracks and monitors, and the digital display makes it clear at a glance.
3. The instrument is equipped with an automatic alarm function for abnormal gas pressure.
4. The gas flow and pressure are digitally tracked and displayed throughout the process.
5. The computer controls the sampler for automatic sampling without manual operation.
6. Personalized operation interfaces and printing formats can be designed according to user requirements.
7. The computer controls the entire process of analysis, data processing, etc., and displays the working status of the whole process.
8. The instrument has the function of recording operation steps and detection processes, and historical operation processes and data records can be queried to meet audit needs.
9. *The nitrogen reaction chamber enhances the reaction intensity between nitric oxide and ozone, and quickly discharges exhaust gas to reduce tailing.
10. It is equipped with an aromatic hydrocarbon barrier filter system with a selective permeable membrane and a detection system, which is impossible to be polluted.
11. The specially made quartz cracking tube, which is免拆换 (no need to disassemble and replace), *solves the shortcoming that the combustion tube is easy to carbonize.
12. The instrument is equipped with a gas filtration and purification system.
13. The key components are imported, which reduces the instrument noise and improves the detection sensitivity.
