    Scope of application
    Visible spectrophotometer, abbreviated as UV, is a chemical valence analysis method.In recent years, UV has played a great role in electronics, electrical appliances, leather, leather goods, toys, food, building materials, metallurgy, geology and minerals, plastics, petroleum, chemical industry, medicine and other industries. UV has special technical advantages such as rapidity and accuracy, and low analysis cost。


    In the field of environmental protection and food, UV can quickly screen out whether the harmful substances in the samples exceed the standard through direct testing.The stability and accuracy of the test are excellent in the rubber and leather industries, such as the hexavalent chromium content of the colorant。


    JV-2000 is widely used to test electroplating coating, and it is widely used to test hexavalent chromium in electroplating ... In addition, UV is widely used in field analysis and process control analysis, such as chemical biology, pharmacy, chemical industry, hospital, environmental protection, sewage treatment and so on。
