1.Built-in computer data processing and LCD screen: Adopts highly integrated computerized digital circuits, stable and reliable. With integral holding, peak height, peak area, auto-zero, adjusting, deuterium lamp background, a variety of linear and nonlinear curve fitting, the screen displays various parameters and working curves, printing reports and other functions, also with an external personal computer interface.
2. Reliable base line stability: optimal design of dual-beam system can compensate for light drift caused by temperature changes the wavelength shift (with the elimination of the baseline stability of wavelength shift function) and the electronic circuit drift, therefore, has a reliable baseline stability cathode lamps do not have to preheating at the long time can immediately analyze samples , analyze a variety of elements and rapid analysis of samples, it is the user's preferred instrument.
3. Measurement accuracy: As gas system is equipped with a precision regulator, steady flow device, flame stability, low noise, the unique design of the light beam could through the fire , ensure the high quality of analysis and testing .
4. High energy optical path: the total reflection optical system, achromatic full band, and a circular light beam by the optical transformation, a spot into the slit length, thereby increasing the double of flux.
5. Long-life corrosion resistance atomization system: burner head with corrosion-resistant, fast thermal equilibrium titanium materials, can achieve stable measurement sensitivity requirements without water cooling.
6. Multi-function analysis method: flame absorption, flame emission, graphite furnace atomic absorption ( AS-3020 autosampler can be equipped) and hydride generation method.
7. Safe and reliable gas system: with fast gas conversion and security guards.
8. Complete accessories: can be used immediately after purchase.
