- Place of Origin: China
- Model Number: WLD-4C
It can be widely used in the fields of casting,metallurgy, shipbuilding,automobile manufacturing and chemical industry etc.
Features:
Reasonable design and perfect performance
Rapid analysis, perfect repeatability and stability
High integrated data collection and control system, high automatic degree
Used for many kinds of matrix analysis: Fe, Co, Ni, Ti, Cu, Al, Pb, Mg, Zn, Sn etc.
High repeatability & stability excitation source is adopted. Excitation frequency can
change in 150 ~ 600 Hz range. Select it based on analysis material user analyzes, to
reach best analysis effect.
Computer software is user-friendly and easy to be operated
Database is built in. User can transfer data through the internet, convenient and quick.
Shake-protection performance is strong, and there is no need to make shake-protection base.
Local constant-temperature technique is adopted to ensure the normal operation,minimizing
requirement to environmental conditions.
Operations and maintenance are easy and convenient, and maintenance cost is low.
