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 3ms/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.
