| Features |
- Various metal bases can be analyzed: ferrous metals of Fe, Co, Ni and Ti base, and non-ferrous metals of Cu, Al, Pb, Mg, Zn and Sn base.
- Adopting the exciting source with high reproducibility and stability. The exciting frequency can be changed in the range of 150 – 600Hz to match the material to be analyzed and get the best analytical result.
- Adopting highly integrated data collecting and controlling system with high automation.
- High-speed analysis with high antijamming ability, good reproducibility and stability.
- Reasonable design with more integrated construction.
- Windows based software with easy and simple operation.
- In-built data base allowing long-distance data transfer.
- Quality control diagram can be established automatically for easy quality control and monitoring.
- High vibration resistance ability. It’s not necessary to make vibration resistance base.
- Partial thermostat system for fewer requirements to the environment.
