    WFX-310/320 Flame Atomic Absorption Spectrophotometer

    FEATURES:

    1 High 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
