Performance features:
The rapid automatic hydrogen analyzer features an integrated design with an elegant appearance, lightweight construction, and excellent maintainability. The entire testing process is controlled by a microcontroller that processes and calibrates test data. It displays the milligram concentration of hydrogen in the sample and prints the measurement results. Each sample analysis takes approximately 10-15 minutes, with accuracy meeting the requirements of China's national standard GB/T15460-2003. Additionally, the instrument can measure carbon using the gravimetric absorption method, ensuring accuracy that complies with the same standard.
※ No restriction on internal water input (internal water>10, results are directly available), effectively preventing experimental failure caused by excessive sample moisture.
