3. Product Features
1. Total reflection optical system, full-band achromatic, automatic wavelength scanning and automatic peak finding.
2. With deuterium lamp button background, self-priming button background.
3. Automatically adjust negative high voltage, lamp current, element lamp position, and adjust energy at will to maximize.
3 hollow cathode lamp holders. Automatic control system, fully automatic scanning wavelength.
1 element lamp works and the other 2 element lamps are preheated.
4. Graphite furnace heating: users can freely set the heating curve according to their needs.
Advanced graphite furnace constant power temperature control design: the temperature of the graphite tube is uniform and consistent, and the working temperature of the graphite tube maintains a good dynamic stability to ensure the accuracy of the analysis. -
