chn analyzerTechnical features:

1. 30 samples can be set out at once, and the instrument can automatically send, drop, experiment, cycle test, and adjust or replace samples at any time during the analysis process.

2. By adopting PID temperature control method, the temperature control accuracy of the furnace can reach ± 1 ℃, and the temperature control accuracy of the constant temperature chamber and gas storage tank can reach ± 0.1 ℃.

3. By using pressure sensors to monitor the pressure of the entire gas path of the instrument, it can automatically perform air tightness checks on the entire gas path, furnace, infrared pool, thermal conductivity pool, and gas storage tank.

4. The instrument adopts ultra-low drift infrared cell and thermal conductivity cell as the core components of element analysis, making the experimental results more accurate and error free.

5. The airtightness detection device with * can detect the airtightness of the gas path in sections under the control of the program, and determine the fault to a specific range. Convenient for gas path maintenance.
