Descripción
Characteristics
1,Completely controlled by PC
2,Integrated floated optical platform design can obviously improve the optical system shock resistance and keep stable though use the optical signal for a long term
3, Eight light standscan be changed automatically and preheat the eight lights meantime as well as optimize the working conditionof the hollow cathode lamp.
4, Position adjusting, the best height of the flame burner and can automatically set the front and rear positions.
5,Fully automated wavelength scanning and peak searching
6,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 flameout.
7,Deuterium lamp and self-absorption background regulation.
8,Data processing: super strong database, possesses more than 500 data self-storage and cut-off storage function, can store the
