L5 / L5S series uv-vis spectrophotometer can meet the daily demand analysis to the scientific research and so on a wide range of application. Instrument adopts advanced reasonable light path system, low noise, the circuit design, has a good reliability and stability.

Features

1. The use of advanced optical, mechanical and electrical design, with outstanding performance and cost performance.
2. The 7 inches color LCD display, operation is flexible and convenient.
3. The proportion of double beam monitoring light path structure, and high performance and low stray light "to shine" holographic grating, the high resolution monochromator, has superior precision, accuracy, reproducibility and stability.
4. Has a unique automatic adjustment "0" "100", eight sample pool linkage.
5. Has the whole wavelength scanning, subband scan, dynamic scanning time, GOTO lambda, linear regression and the concentration of the direct reading, peak detection and other advanced work.
6. Use thermal plotter, data can be printed, spectral scan, drawing the wavelength scanning time, linear regression, etc.

With USB interface, can be directly interact with a PC, strengthened the instrument of testing data, scanning map processing functions, such as implementing the test documents mass storage, and secondary development provides the convenience for the user.

1. Advanced electricity protective measures, can the memory test data, scanning atlas, regression equation and the revised of instrument, etc., realized the quick initialization boot into the test state.
2. The instrument USES high-energy long-life flange positioning deuterium lamp. When the instrument deuterium lamp must be replaced, as long as the uninstallation two flange positioning screw,
