Introduction
The 757 UV/VIS Spectrophotometer can meet the needs of a wide range of applications, from routine analysis to scientific research. The biter adopts a professional proportional dual-beam optical path system and a low-noise circuit design, which has good reliability and stability.
Features
It adopts professional optical, mechanical and electrical design, and has excellent performance and cost performance.
It adopts 8-inch color touch LCD display, which is flexible and convenient to operate.
It adopts a proportional dual-beam optical path structure and is equipped with a high-performance "shining holographic light shed" with a low-stray light and high-resolution monochromator, which has excellent optical accuracy, measurement accuracy, reproducibility and stability.
Featuring a unique auto-adjust "0" to adjust to "100", an automatic 8-well sample holder.
It has various advanced functions such as kinetic time scanning, GOTOλ, linear regression, concentration direct reading, peak-to-valley detection, etc.
Using thermal plotter (optional), it can draw curves such as data printing, spectral scanning, fixed-wave long-term scanning, and linear regression.
With USB interface, it can directly interact with the PC through the standard UVwin8 ultraviolet spectroscopy software, which strengthens the processing functions of the instrument's detection data and scanning spectrum, realizes the massive storage of test documents, and also provides convenience for users' secondary development.
Professional power-off protection measures, which can memorize the measured data, scanning spectrum, regression equation and instrument correction value, etc., and realize the rapid initialization of the boot into the test state.
The instrument uses a high-energy, long-life flange to locate the neon lamp. When the neon lamp needs to be replaced, only two flange positioning screws need to be removed and installed to ensure that the lamp source is in the right position without cumbersome optical path adjustment.
