Manufacturer : RAYLEIGH
ISO 9001: 2000 & ISO 4001: 2004
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
