759S UV Visible spectrophotometer

Main features:
Adopting advanced optical, mechanical, electrical, and microcomputer modular design, it has outstanding performance and cost-effectiveness.
Adopting a proportional dual beam optical path structure and equipped with a high-performance "sparkling holographic grating" low stray light high-resolution monochromator, it has outstanding optical accuracy, measurement accuracy, reproducibility, and stability.
Equipped with powerful microprocessing capabilities, fully automated system operation, testing control, and data processing, it has a unique automatic adjustment of "0", "100", eight sample pool linkage, and light source reflector micro step switching technology.
It has various advanced functions such as full band scanning, sub-band scanning (with 759S host), dynamic time scanning, GOTO λ, linear regression, concentration direct reading, peak valley detection, etc.
Using a thermal plotter, data printing, spectral scanning (with 759S host), fixed wavelength time scanning, linear regression and other curve drawing can be performed. 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.
Reliable power-off protection measures, capable of memorizing measured data, scanning spectra, regression equations, and instrument correction values, and achieving rapid initialization and testing upon startup.
The instrument is easy to operate, and users only need to select and confirm the corresponding menu on the LCD screen to achieve the desired function.
The instrument adopts high-energy long-life flange positioning deuterium lamp. When the deuterium lamp of the instrument needs to be replaced, only two flange positioning screws need to be removed to ensure that the lamp source is in the best position, without the need for tedious optical path adjustment.
