Product Details
AAS 4530F Complete automatic controlling system:With the help of the software, the following can be easily achieved:
1.Selection of the element lamp
2.Up-down-front-rear adjustment of the lifter
3.Adjustment of the optical energy
4.Selection of the slit
5.Determination of wavelength scanning and peak searching
6.Selection of the atomizer
7.Setting of the background deduction method 
8.Controlling of the gas flow
9.Automatic flaming and flaming out 
10.Setting of the graphite furnace testing method
Completely controlled by PC, can flexibly select the flame and graphite furnace atomizer (optional).
.Integrated floated optical platform design can obviously improve the optical system shock resistance and can keep stable though use the optical signal for a long term.
Eight light stands can be changed automatically and preheat the eight element lights meantime as well as optimize the working condition of the hollow cathode lamp.
Position adjusting: the best height of the flame burner and can automatically set the front and rear positions.
Fully automated wavelength scanning and peak searching.Deuterium lamp and self-absorption background regulation.
Complete safety chains protection equipment: the function of warning and automatic safety protection towards the wrong burner, leakage of the gas, under voltage of air and the abnormal flame out.
Data processing: super strong database, possesses more than 500 data self-storage and cut-off storage function.
Measuring method: flame absorption method and emission method.Result printing: parameter printing, data result printing and diagram printing.
