GA3202 Graphite Furnace

I.Introduction

GA3202 graphite furnace control system is designed for graphite furnace atomic absorption spectrometry to make the quantitative analysis substance of the of trace elements, is an important accessory for atomic absorption spectrometer .

II.Features

Features:

1. This product updates the original monolithic control system, with photoelectric rapid heating temperature control function, can external data station and displays the temperature and the absorption curve.

2. LCD backlight character graphics display. Menu operation, the setted temperature,parameters and curves can be remembered , needn't to adjust again at next test (without batteries).

3. The simplified wiring conduit through furnace to connect to atomizer conversion device , which greatly provide the convenience for graphite furnace installation and commissioning, and can achieve the quick switching betwenn flame method and graphite furnace method .

4. The system uses pneumatic closed structure, to ensure constant pressure, reliable contact and offers protection and argon pressure monitoring for overheating, over-current, over-power .
