UV1900 UV-Vis Spectrophotometer Violet Visible Light Double Beam


1. The real double beam metering system, with advanced circuit measurement and control system, make the instrument with high reliability and low noise.

2. Unique installation of deuterium lamps and tungsten lamps, the design and working way of automatic light switch and finding the best location, allowing users to operate the instruments and maintain or replace light source in a more convenient ,correct and safer way.

3. Excellent software design and procedure, make instruments have stronger spectral data processing function: automatically scan measured spectra, multi-wavelength (1-3λ ) determination, kinetic determination, 1-3 curve fitting, 1-4 derivative spectra, access ,display, print spectra and analyze data.

4. Powerful Windows-based software platform, user-friendly, powerful, easy to store or output, and to facilitate business, save costs.

5. The software and external appearance can be customized according to customer's requirement.
