Lab analysis instrument Dual-beam ultraviolet-visible
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
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.
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
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.
