The instrument uses pulsed xenon lamp as the light source. The instrument is used normally for at least 7 years, no need to replace the light source, and the user's instrument use cost is minimized. We use original optical, circuit, structural design, advanced process specifications and strict quality management system to create this international advanced level, to meet user needs and usage habits. Microcomputer control and processing data, large-screen color display, graphical interface operation and user-friendly menu prompts, ready to draw spectral maps and analyze test data. It has many functions such as photometric measurement, automatic scanning measurement spectrum, quantitative analysis, and dynamic spectrophotometry. The sensitivity and accuracy of the analysis are high; the spectral data processing function is strong; the Chinese man-machine dialogue is convenient, the operation is convenient; the appearance of the instrument is beautiful and generous.
