Flame
The AAS is fully PC controlled with modern
and compact design. They have flexible configuration and different accessories
to meet variable requirements. Advance optical system can guarantee stable and
reliable performance. Unique and intelligent gas control module can ensure the
device safety. The AAS can test more than 70 elements including metallic and
non-metallic elements, which can be used widely in petrochemistry, metallurgy,
mining, geology, material analysis, food and pharmacy.
Main Features
1. Total reflection optical system can
reduce energy loss to ensure better signal-to-noise ratio and lower detection
limit.
2. Standard deuterium lamp background
correction for all models. Standard high-performance self-absorption background
correction for double beam models, and optional for the models with 8-lamp
turret.
3. Automatic pneumatic control module
ensures the device safety and accuracy and protects the operator and device
better.
4. Automatic vertical 4/8-lamp turret supports
high-performance element lamp, can be rotated 360 degrees and make sure the
test accuracy and reliability is not affected by the gravity.
5. Automatic burner adjustment ensures the
maximum sensitivity, you can raise or lower the burner according to the
reading. Flame detection enhances the device safety.
6. Modular design for optical system and
circuit makes the maintenance and repair simple.
7. Professional, automatic and easy to
operate full operation RGWIN AAS software under MS window system and QA/QC
function.
8. Safety protection system: flame monitoring (acetylene will be turned off automatically if there is any abnormality and show warning information), unique acetylene protector (warning information will be shown if the leak acetylene concentration is beyond the alert concentration), pressure monitoring (the flame will not work if the air or acetylene pressure is not normal.
