Introduction: JH-UV5 ultraviolet visible spectrophotometer has friendly interface and easy operation. The host is equipped with dot matrix liquid crystal display, which can be used for photometric measurement and quantitative test, and the standard curve graph can be displayed directly. PC scanning analysis software can be selected to expand the functions of wavelength scanning, time scanning, multi wavelength testing and nucleic acid protein testing. It is widely used in life science, material science, environmental science, agricultural science, metrology science, food science, geological science, petroleum science, medical and health, iron and steel metallurgy, chemical and other fields. characteristic: 1. High quality optical and electronic components ensure high precision and low stray light; 2. Automatic wavelength calibration, automatic dark current and blank correction, automatic switching light source and filter; 3.
