Description
1 Built-in computer data processing and liquid crystal display: the use of highly integrated computerized digital circuits, stable and reliable. With a variety of linear nonlinear curve fitting, the screen displays a variety of parameters and work curves, print reports and other functions, at the same time with an external personal computer interface.
2 Reliable baseline stability: Optimized design of the dual-beam system can compensate for drift of the light source, temperature changes caused by wavelength drift (with the effect of eliminating wavelength drift on the baseline stability of the function) and electronic circuit drift, therefore, with reliable baseline stability , The cathode lamp does not have to be preheated for immediate analysis of the sample, is the analysis of a variety of elements and rapid analysis of the sample users preferred instrument.
3 High precision of measurement: As the air system is equipped with precision regulator, steady flow device, flame stability, low noise, unique design of the fine beam from the flame through to ensure that the analysis of high precision, low characteristic concentration.
