Products description:1. Super big LED display directly, no need PC support. And also can connect with a PC if needed.2. The mainframe with DC power supply inside which can power the standard lightsource directly when calibration.3. With the strength of fast speed which can improve the efficiency.3. Good human-machine interface with windows operate system, SA905 standard interface and CCD high-speed optical spectra. Connect with a printer can print test report directly, and data can be save as Excel file for analysis purpose. A mainframe with related devices can fully satisfied with the photic, chromatic and electric analysis and other experiments like this. It is applied to labs, QC department and also production line.CHRACTERISTICS AND SPECIFICATIONS1.
