WFX-320 Flame Atomic Absorption Spectrophotometer
Features
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 easy operation
Eye-catching digital display, multi-function data processing ability and fast function-key direct input realize easy and fast analysis.
