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. The uniquely designed all-titanium burner has smooth combustion and fast heat balance. 4. Automatic adjustment of negative high voltage, lamp current, automatic adjustment of the best element lamp position, automatic ignition, automatic flameout protection. 8 lamp stands (optional 2 high-performance lamps) automatic control system, which can adjust the hollow cathode lamp to the best position in all directions, can set the lamp position of a specific element independently, and can freely set the working lamp, preheating The lamp saves the element lamp preparation time to the greatest extent possible. 5. 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.
