  Characteristics :

  1.       built in computer data processing and LCD, adopting highly integrated micro digital circuit, which is stable and reliable with the functions of integral holding, peak height and area, auto zero adjusting , deuterium lamp and background,multi-linear and nonlinear curves fitting, various parameters and working curves displayed in screen and report printing, etc ,it is euipped with interface for externally linking PC

  2.       Good basic line stability, double beam system of optimized design can automatically compensate the light source drift and wavelength drift caused by the variation of temperature with the function of the eliminating the affection of wavelength drift on the base line stability and electronic circuit drift so as to reach a good basic line stability , the cathode lamp needs not be preheated for long time and sample can be analyzed immediately , it is the preferable instrument chose by user to conducts analysis of multiple kinds of elements and fast analysis of samples

  3.       High precision of measurement , gas path system is quipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise , specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration

  4.       Optical path of high energy, atotal reflection system is adopted to eliminate color difference in full range , by means of chemical conversion , a round light spot of the light source becomes a long light spot, which enters into the slit, therefore the light flux of double beam is enhanced

  5.       long life and anti corrosive atomization system , the burner is made of new type titanium alloys, anti corrosive and fast thermal equilibrium ,it meets the requirement of measurement sensitivity without water cooling

  6.       multi functional analysis mode for methods of flame absorption ,flame emission graphite furnace atomic absportion AS-3020 automatically sample feeder can be installed , and hydride generation

  7.       safe and reliable gas path system : specially devices of quick gas conversion and safety protection can be used to analyze air acetylene flame as well as nitrous oxide-acetylene flame and extend the analytic elements to reach more than 60

  8.       complete set of accessories , to be supplied with the instrument and ready for use after they are purchased
