Lab analysis instrument Dual-beam ultraviolet-visible spectrophotometer
It is a dual-beam automatic scanning ultraviolet-visible spectrophotometer. Adopts optical system design, microcomputer control and data processing, large-screen LCD Chinese window display operation menu, spectrogram and analysis test data. With functions of photometric measurement, automatic scanning measurement spectrum, quantitative analysis, dynamic spectrophotometric analysis and so on. Easy operation; beautiful appearance.
It is widely used in fields of drug inspection, medicine and health, biochemistry, environmental monitoring, commodity inspection, petrochemical industry, ferrous and non-ferrous metallurgy, etc. It is the basic equipment of quality control, technical appraisal and scientific research institute.
Features
The host has excellent optical performance and photometry performance, low stray light, high photometry and stability.
The double-beam photometry system, combined with the circuit measurement and control system, enables the instrument to have high and low noise.
The deuterium lamp and tungsten lamp are installed, the light source is automatically switched and the position is automatically searched for the design and working mode, so that users can operate the instrument and repair the replacement light source conveniently and correctly.
It adopts large-screen Chinese window (LED) LCD display, and has a good man-machine dialogue interface.
The excellent software design and programming enable the instrument to have strong spectral data processing functions: automatic scanning of measurement spectra, multi-wavelength (1-3λ) determination, kinetics determination, 1-3 curve fitting, 1-4 order derivative spectroscopy, Access, display, print, and analyze data.
The software developed based on the Windows platform has a friendly interface, which is convenient for your storage output, convenient for office work, and cost-saving.
