Product Description

The L9 dual beam UV visible spectrophotometer adopts an optical system design, with five adjustable bandwidth levels. The ARM chip controls and processes data, and an 8-inch color touch screen displays menus, spectrograms, and analysis test data. The human-computer interaction operation is simple. The instrument has functions such as photometric measurement, automatic scanning spectroscopic measurement, quantitative analysis, kinetic analysis, and multi wavelength measurement. The product is widely used in the fields of drug inspection, pharmaceutical and health, biochemistry, environmental monitoring, commodity inspection, petrochemicals, etc. It is a basic equipment required for quality control, technical appraisal, and scientific research.
