L8/L9 Double Beam UV-VIS Spectrophotometer

The L8/L9 double beam UV-Vis spectrophotometer applies a new optical bench, with 5-speed adjustable bandwidth, ARM chip control, and data processing, an 8-inch color touch-screen that displays a menu, and spectral curve, and can analyze spectrum test data. It’s quite easy for user and computer interaction. The instrument can perform the 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.
