Atomic Absorption Spectrometer

High cost-effective flame AAS

Reasonable design, adopting the same key parts as in high end instruments, ensures basic functions 

but less automation to provide an economic model for users

Reliable integration of main unit with microprocessor

Built-in microprocessor with necessary auto-control and data processing functions achieve high 

reliability of the instrument.

Simple and East Operation 

Eye-catching digital display, multi-function data processing ability and fast function-key direct 

input realize easy and fast analysis.
