Basic features:
Low built-in LCD screen and computer data processing: the high integration of microcomputer digital circuit, stable and reliable.With integral keep, peak height and peak area, automatic zero, deuterium lamp button background, multiple linear non-linear curve fitting, screen display various parameters and working curve, print reports, and other functions, is equipped with an external PC interface at the same time.
Low reliable baseline stability: the optimization design of double beam system can compensate drift, wavelength drift caused by the temperature variation (with the elimination of the influence of wavelength drift to baseline stability function) and electronic circuit drift, therefore, has reliable baseline stability, cathode lamp preheating can analysis sample immediately, do not have long-term is to analyze a variety of elements and quickly analyze the user preferred instrument of the sample.
Low measurement precision: due to the pneumatic system is equipped with precision voltage regulator, steady flow device, flame stability, low noise, fine beam from the flames, through the unique design, to ensure that the analysis of characteristics of high testing precision, low concentration.
Low energy light path: the total reflection optical system, all band achromatic, circle and will light light through the optical transformation, become a long light into the slit, so as to improve the luminous flux of the double beam.
Of long life and low corrosion resistance of the atomization system: the combustion head corrosion resistance, rapid heat balance new titanium alloy material, can achieve measurement sensitivity stability without water cooling requirements.
Low utility analysis method: to do the flame absorption, emission, graphite furnace atomic absorption (AS - 3020 automatic sampler can match) and hydride method.
Low gas circuit system of safe, reliable, fast gas conversion and safety protection device.
Low attachment is complete: randomized complete, can use after purchase.
lowAA320NCRTAttached to the brand computer, data acquisition software.
