DSH-L6/L6S Series UV-Vis Spectrophotometer


Technical Data Sheet


 DSH-L6/L6S Series UV-Vis spectrophotometer could meet the daily analysis

 of a wide range of scientific applications. Instrument uses advanced and reasonable optical system,

 low noise circuit design, with excellent reliability and stability.


 II.Main features

 1. Adopts advanced optical, mechanical, electrical design, with superior performance and cost.

 2. 7-inch color touch LCD display, flexible operation.

 3. Adopts proportion of double-beam optical path monitoring structure, high performance, low stray light "shining holographic grating",

 high-resolution monochromator with superior accuracy, veracity, reproducibility and stability.

 4. With a unique automatic adjustment "0" adjustment "100", eight sample cell linkage.

 5. With full band scan, sub-band scanning, kinetics time scanning,

 GOTOλ, linear regression, the concentration of direct reading, peak detection, and other advanced features.

 6. Use of thermal plotter, data can be printed, spectral scanning, fixed wavelength time scanning, linear regression curve drawing.

 7. With USB interface for direct interaction with the PC, and strengthen the instrument's detection data, scanned maps and other processing

  functions to achieve the test documentation mass storage, but also for the user to provide a convenient secondary development.

 8. Advanced power protection method measurement, can remember the test data, scanned maps, the regression equation and

  instrumentation correction value, etc., to achieve a fast initialization boot into the test state.

 9. The instrument uses high-energy, long-life deuterium lamp positioned flange. When the instrument deuterium lamp must be replaced, just uninstall two flange screws,

 you can ensure that the light source in the best position to adjust the optical path without tedious.
