Espectrofotómetro de absorción atómica-AA320N Plus

Main Features
Integrated flame and graphite furnace system with quick and easy switching between flame and graphite furnace atomizers.
The optical platform is integrally cast, featuring excellent anti-vibration performance and a more stable optical system, with minimal light loss and high sensitivity.
Equipped with a full-wavelength, high-resolution symmetric aberration-corrected Czerny-Turner monochromator for ultra-accurate wavelength positioning.
4-lamp automatic rotating turret with simultaneous preheating function to optimize operating conditions.
Built-in storage for over 500 sets of data with power-off memory; test methods and results can be retrieved at any time.
Standard configuration with a fully functional workstation software for user-friendly operation (audit trail function available as an option).
Advanced and precise graphite furnace temperature control technology, combined with a self-diagnostic and protective system for equipment faults.
