Adopting a parallel dual beam optical system. Innovatively achieved a layered layout of optical and circuit systems. 10.1-inch ultra high definition high-sensitivity color touch screen and high-performance built-in chip, with clear display and smooth touch control. And it has a large storage capacity of 3G, which can fully meet the application needs of various complex experimental scenarios. 0.025nm ultra narrow wavelength interval enables high-resolution analysis – the extremely small interval setting can fully restore the spectral peak shape, accurately identify the characteristic peaks of trace components, effectively avoid information loss caused by wide intervals, and significantly improve the accuracy and reliability of qualitative and quantitative analysis.
Features
Excellent dual beam optical system, higher instrument resolution, lower stray light, stronger stability and reliability, and more accurate analysis;
Adopting a 10.1-inch four layer composite true color capacitive intelligent touch screen, the touch screen is sensitive, and the data and spectrum display are clear;
Complete data analysis functions, the host can independently complete functions such as photometric measurement, quantitative measurement, spectral scanning, kinetics, DNA/protein testing, multi wavelength testing, and data printing;
The main components adopt imported configuration, which reduces instrument stray light and enhances stability and reliability;
The storage function is complete, and data can be exported to a USB flash drive. The instrument can be directly connected to a printer for A4 format data and graph printing;
Optional spectral scanning software, when operated online, can not only achieve all testing functions of the host, but also complete more powerful data processing functions;
Open platform, providing a foundation for complex secondary development functions;
The software follows the GLP/GMP laboratory usage standards and comes with comprehensive user management, logging, data storage traceability, and report output functions;
Easy to use accessories such as automatic eight cell holder, micro colorimetric dish holder, constant temperature automatic sampler, reflective accessories, rotating solid sample holder, etc., to meet users’ multidimensional testing needs and expand the application field of the instrument.
