Features:
1. The flame system uses high-precision mass flow controllers for precise automated flow control.
2. The constant transverse magnetic field Zeeman background correction technology provides superior full-spectrum background absorption correction capability.
3. Built-in cooling water detection and temperature monitoring ensure reliable operation of the magnetic field system.
4. The patented quick-release burner head design solves cleaning challenges, allowing tool-free disassembly in just 3 seconds.
5. A complete gas-liquid separation system and fuel filtration unit ensure stable operation in high-humidity environments or with limited gas supply.
6. Multiple safety interlock mechanisms with automatic shutdown and alarm functions protect against operational anomalies.
7. The modular instrument design and circuit architecture enable easy maintenance and quick component replacement.
