Build-in computerized 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 equipped with interface for externally linking PC Built in computer data processing and LCD: adopting highly integrated micro digital circuit,

which is stable and reliablewith the functions of integral holding, peak height and area, auto zero adjusting,

It is equipped with interface for externally linking PC

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 chosen by users to conduct analysis of multiple kinds of elements and

fast analysis of samples.
