UV Visible Ratio Dual Beam Spectrophotometer

Product Description

The application of high-performance 1200L/mm ultraviolet special grating, combined with a unique monochromator optical path and the fusion of imported photoelectric converter, ensures the low stray light, high resolution, and high light seat embroidery of the instrument.
The spacious sample room allows for a maximum selection of 10cm samples according to different requirements, meeting the needs of special industries.
The use of imported long-life lamps and tungsten lamps ensures the high-quality requirements of the instrument for light source energy, enabling the instrument to remain in a high stability state for a long time, enhancing reliability, and extending the service life of the instrument,
Equipped with advanced automatic wavelength error correction function, it further ensures the testing accuracy of the instrument. The perfect integration of the computer and the host is ensured. The large screen has a color interface with a touch screen display screen, matched with large-scale integrated circuits, making it highly intelligent and automated, reflecting a sense of technology and smooth use. Convenient, seamless, fresh and intuitive reading of the relevant data of the test sample, the spectrophotometer has testing functions such as photometric, quantitative, regression formula, kinetics, home wavelength, DNA/protein concentration, peak valley detection, etc.
The configuration of specialized software enables the fast device to have strong memory function, allowing it to recover the testing status of Xundi and memorize the relevant data that has been tested when restarting at a high speed. By adding curves and graphs, it facilitates the export of relevant data and Tuno curves, and can also import the saved data parameters and graphs into a worksheet for comparison and analysis with the current testing chart. The USB interface can be used to speed up peripheral devices and related operating tools such as computers, printers, specialized software, keyboards or standards.
