Features:
1. Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer(optional).
2. Integrated floated optical platform design improves the optical system shock resistance stable.
3. Eight light stands can be changed automatically and preheat the eight lights meantime as well as optimize the working condition of the hollow cathode lamp.
4. Position adjusting: the flame burner can be set on the best position automatically.
5. Fully automated wavelength scanning and peak searching.
6. Complete safety chains protection equipment: warning and automatic safety protection for the wrong burner connection, leakage of the gas, under voltage of air and the abnormal flameout.
7. Deuterium lamp and self-absorption background calibration.
8. Measuring method: flame absorption method and emission method.
9. Result printing: parameter, data result and diagram.
10. Data processing: more than 500 data self-storage and cut-off storage, the analyzed result is stored in EXCEL format.
