Product Details

    The L5S (759S) series UV visible spectrophotometer can meet a wide range of application needs, from daily analysis to scientific research. The instrument adopts advanced and reasonable optical path system, low-noise circuit design, and has excellent reliability and stability.

    主要特点

    Adopting advanced optical, mechanical, and electrical designs, it has outstanding performance and cost-effectiveness.

    ★ Equipped with a 7-inch color touch LCD display, the operation is flexible and convenient.

    ★ Adopting a proportional dual beam monitoring optical path structure and equipped with high-performance "shimmering holographic grating"A monochromator with low stray light and high resolution,Has outstanding optical accuracy, measurement accuracy, reproducibility, and stability.

    ★ It has a unique automatic adjustment of "0" to "100" and linkage of eight sample pools.

    ★ It has various advanced functions such as full band scanning, sub-band scanning, dynamic time scanning, GOTO λ, linear regression, concentration direct reading, peak valley detection, etc.

    ★ Optional thermal plotter, capable of data printing, spectral scanning, fixed wavelength time scanning, linear regression and other curve drawing.

    ★ Equipped with a USB interface, it can directly interact with a PC, enhancing the instrument's detection data, scanning spectra and other processing functions, achieving massive storage of test documents, and providing convenience for users' secondary development.

    ★ Advanced power-off protection measures, capable of memorizing test data, scanning spectra, regression equations, and instrument correction values, and achieving fast initialization to enter testing mode upon startup.

    The instrument adopts high-energy long-life flange positioning deuterium lamp. When the deuterium lamp of the instrument needs to be replaced, simply remove the two flange positioning screws to ensure that the lamp source is in the optimal position, without the need for tedious optical path adjustment.
