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

Complete safety 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

◆ Deuterium lamp and self-absorption background regulation

Data processing: super strong database, possesses more than 500 data self-storage and cutoff storage function, can store the analyzed result with the form of EXCEL and the testing method and the result can be randomly called

◆ Measuring method: flame absorption method and emission method

◆ Result printing: parameter printing, data result printing and diagram printing

Complete automatic controlling system 

With the help of the software, the following can be easily achieved

Selection of the element lamp

Up-down-front-rear adjustment of the lifter

Adjustment of the optical energy

Selection of the slit

Determination of wavelength scanning and peak searching

Selection of the atomizer

Setting of the background deduction method

Controlling of the gas flow

Automatic flaming and flaming out

Setting of the graphite furnace testing method

Advanced graphite furnace temperature controlling technology

The bringing in of PID technology can effectively overcome the influence on the temperature rising process caused by the voltage fluctuation and the resistance change to make more accurate controlling process.

The combination of the 3/time fast sampling technique can make more accurate and reliable testing data

The fast heating capacity can improve the flexibility of the elements further

Use the ordinary power source of 220V without need of dynamic power of 380V

The maximum procedure heating capacity setting of 20 levels can make a more convenient and easier test of different samples

Three grades adjustable gas flow can accustom to more application needs

Can timely alarm when the gas and water is stopped and insufficient gas and water, can avoid the equipment damage and measuring error Safe, reliable and convenient flame system

Epc can control the flow of Acetylene (C2H2) more accurately and it is a kind of system which also can operate easily

Efficient Atomization system enables a higher sensitivity

The whole operation system has a high security as the fire safety system can alarm whenever the electricity is cut off, Abnormal flame occurs,

a lack of pressure happens or the burner does not match well. And it will automatically turn off the gas, prohibit tempering. Thus it keeps the operation people and equipment from harm and damage.

Multi-functional software workstation

A workstation that is supported WINDOWS 10

The rich menu brings great convenience to the use of customer

Convenient conversion between different menus makes the operation more easily
