6. Circuit system

The circuit system uses  large-scale integration, and all large-scale integrated circuit boards which are industrial-grade electronic components and welded mechanically to ensure the stability and reliability of long-term operation. The power supply system has two solid-state power modules. The power supply module has a short circuit protection function, is resistant to current impact, is dust-proof, simple and reliable; the connection uses a shielded flat wire connector, which eliminates the potential for failure caused by poor contact, and improves the reliability of the entire circuit and the connection reliability between lines. The data transmission lines of circuit system and other circuits have professional anti-interference measures to reduce the impact of electromagnetic interference.

7. The whole machine structure

The whole machine  use a modular and integrated design, with four independent modules: high-frequency furnace, gas circuit system, circuit system, and infrared detection system. The high-frequency furnace is equipped with professional anti-high-frequency leakage devices, and the entire circuit system has anti-electromagnetic interference devices;  avoiding the unstable analysis results caused by high-frequency interference or electromagnetic interference and the impact of high-frequency radiation on the human body.
