L6S / L6 UV-Vis spectrophotometer uses advanced ratio of dual-beam optical system, low-noise circuit design, with excellent reliability and stability. Can meet the daily analysis to the scientific research and so on a wide range of application needs.

main feature:

● 8-inch color touch LCD display, flexible and convenient operation.

● High-performance monochromator with low-stray light and high-performance “shiny holographic grating” with high-performance, high accuracy and reliability. It has excellent cost performance The

● With a unique automatic adjustment “0” adjustment “100”, automatic 8-hole sample rack.

● With full-band scanning (limited to S), sub-band scanning (limited to S models), dynamic time scanning, and GOTOλ, linear regression, concentration direct reading, peak and valley detection and other advanced features.

● Optional thermal plotter, can be data printing, spectral scanning (limited to S) fixed wavelength scanning, linear regression curve drawing.

● With USB interface, combined with UVwin8 UV spectrum software, can directly interact with the PC, to strengthen the instrument detection data, scanning maps and other processing functions, to achieve the test file mass storage, but also for the user to provide a second development.

● advanced power protection measures, can remember the measured data, scan patterns, regression equations and instrument correction values, and to achieve a quick start to enter the test state.

● The instrument uses high-energy imported long life flange positioning deuterium lamp. When the instrument deuterium lamp must be replaced, just unload the two flange positioning screws, you can ensure that the light source in the best position, without cumbersome optical path adjustment.

Optional:

● Thermal drawing printer

UVwin8 UV spectrum software
