  • Description
  • Feature
    7-inch color touch screen and patented technology to achieve a simple and effective human-computer interaction at the same time,clearly show the test data and scan results.
    USB communication port and optional UVwin8 UV spectrum software, to achieve data and map processing functions, as well as massive data storage, and for the customer's secondary development to facilitate.
    Full-band scanning (limited to S), sub-band scanning (limited to S), dynamic time scanning, automatic wavelength, linear
    regression, concentration direct reading, peak and valley detection, timing printing and other functions.
    Advanced power protection measures, you can remember the test data, scan map (limited to S models), regression equations and instrument correction parameters, to achieve rapid initialization.
    With halogen and deuterium lamp life protection.
    Light source: 12V 20W halogen lamp and long life deuterium lampPower:180W
