The GA3202 graphite furnace system is a specialized system for quantitative analysis of trace elements in substances using graphite furnace atomic absorption spectrometry, and is an important optional accessory for the AA320N atomic absorption spectrophotometer.

Main features:

Equipped with photoelectric rapid temperature rise and control function, it can be connected to an external data station and display temperature and absorption curves.

LCD backlit display of characters and graphics. Menu based operation, capable of memorizing the set heating program parameters and curves for the next call.

A single wiring pipeline is connected to the double atomizer conversion device through the furnace body, greatly facilitating the installation and commissioning of the graphite furnace, and enabling rapid switching between the flame method and graphite furnace method analysis methods.

The system adopts a pneumatic closed structure to ensure constant pressure, reliable contact, and is equipped with overheat, overcurrent, and over power protection as well as argon pressure monitoring.
