3. Product Features
1. Total reflection optical system, full-band achromatic, wavelength scanning and peak-seeking.
2. The specially designed all-titanium burner has stable combustion and fast heat balance.
3. Automatically adjust negative high voltage, lamp current, and automatically adjust the best element lamp position.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.
4. It can be upgraded to graphite furnace atomic absorption spectrophotometer. -
