Features:
Built-in computer data processing: the instrument features integrated computer data processing and an LCD display for easy and efficient operation.
Stability: the double-beam system compensates for light source drift and wavelength drift caused by temperature changes and electronic circuit variations, ensuring stable readings.
Rapid analysis: the cathode lamp does not require long pre-heating times, allowing immediate analysis of samples.
High precision measurement: equipped with a precision pressure stabilizing and current stabilizing system, the gas path ensures a stable flame with low noise, enabling precise analytical tests and low characteristic concentration.
High-energy optical path: designed with a high-energy optical path for improved signal detection and measurement accuracy.
Durable atomization system: the long-life, anti-corrosive atomization system ensures longevity and resistance to wear.
Multi-functional analysis modes: supports various analysis modes including flame absorption, flame emission, graphite furnace atomic absorption, and hydride generation for versatile applications.
Safe and reliable gas path system: the system includes special safety devices for quick gas conversion, capable of analyzing air-acetylene and nitrous oxide-acetylene flames, allowing for the analysis of over 60 elements.
