The patented flame analysis technique adopting oxygen rich air acetylene flame as the substitution for nitrous oxide-acetylene flame for high temperature element analysis, such as Ca, Al, Ba, W, Mo, Ti, V, etc. Flame temperature is continuously adjusted between 2300-2950°C,which makes it possible to choose the best atomization temperature for different elements.
It features easy operation, low analysis cost.
Accurate automatic operation.
6-lamp turret automatic changeover, automatic adjustment of the lamp supply power, automatic optimize spectral beam position.
Automatic wavelength scanning and peaking.
Automatic spectral bandwidth selection.
Automatic igniting.
Perfect safety protection measures: Alarm and automatic safety protection to fuel gas leakage, air pressure deficiency and abnormal flame extinction.
Adopting large-scale programmable logic array and inter IC bus technology with advanced electronic design.
AMP adapters with high reliability to ensure long term reliability of the whole electric system.
