L9 Double Beam UV-VIS Spectrophotometer

L9 Double Beam UV-VIS Spectrophotometer

Product Details

The L9double beam UV-Vis spectrophotometer applies a new optical bench, with 5-speedadjustable bandwidth, ARM chip control and data processing, 8-inch color touch-screen which displays menu and spectral curve and can analyze spectrum test data. It's quite easy for user and computer interaction. The instrument can perform following operations, including photometry, automatic scanning spectral measurement, quantitative analysis, dynamic analysis, and multi-wavelength measurement.

The instrument serves as the basic equipment for quality control, technical evaluation and scientific research, and can be widely used in susceptibility testing, medicine and health, biochemistry, environmental monitoring, commodity inspection, petrochemical and other fields.

Main Features

● New optical platform, enabling the host machine with excellent optical properties, metering performance, low stray light and noise, high metering accuracy and stability.
● Unique system of deuterium and tungsten lamp installation, facilitating the light source to automatically switch to the best position, and allowing users to operate the instrument, replace the light source and maintain the instrument more conveniently, accurately and safely.
● Sophisticated hardware and software design, empowering the instrument with powerful spectral data processing and storage capabilities, and performing following functions,including automatic scanning of measured spectrum, multi-wavelength (1-3 λ) measurement, kinetic measurement, 1-3 curve fitting, 1-4 derivative spectra, spectra printing and storage and data analysis.
● 8-inch color touch-screen, with a good user-machine interface, easy-to- operate.
● USB communication port.
