The L9/L8 double beam UV-VIS spectrophotometer applies a new optical bench, with 5-speed adjustable bandwidth (9 only), 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 basic equipment for quality control, technical evaluation and scientific research, and can be widely used in susceptibility testing, medicine and health, biochemistry inspection, chemistry, environmental monitoring, commodity inspection, petrochemical and other field.
Feature
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, 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 safety.Sophisticated hardware and software design, empowering the instrument with powerful spectral data processing and storage capabilities, performing following functions, including automatic scanning of measured spectrum, multi-wavelength ( 1-3 λ) 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.USD communication port
