FLAME ATOMIC ABSORPTION SPECTROPHOTOMETER MODEL NO.- ACM--FAAS-2687
R
FLAME ATOMIC ABSORPTION SPECTROPHOTOMETER
FEATURES 타 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 타 Built-in microprocessor with necessary auto-control and data processing functions achieve high reliability of the
instrument 타 Eye-catching digital display, multi-function data processing ability and fast function-key direct input realize easy
and fast analysis
