Advanced graphite furnace temperature controlling technology:
The bringing in of PID technology can effectively overcome the influence on the temperature rising pr℃ess caused by the voltage fluctuation and the resistance change to make more accurate controlling pr℃ess. 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 pr℃edure 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 ℃curs, 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.
