Flame Atomic Absorption Spectrophotometer

Flame Atomic Absorption Spectrophotometer
Product Detailed
Flame Atomic Absorption Spectrophotometer High cost-effctive flame AAS

Flame Atomic Absorption Spectrophotometer

Features

1High cost-effctive 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

2 Reliable integration of main unit with microprocessor

Built-in microprocessor with necessary auto-control and data processing functions achieve high reliability of the instrument

3 Simple and easy operation

Eye-catching digital display, multi-function data processing ability and fast function-key direct input realize easy and fast analysis
