Visible spectrophotometer, abbreviated as UV, is a chemical valence analysis method. In recent years, UV has played a great role as a rapid detection method in electronics, electrical appliances, leather, leather goods, toys, food, building materials, metallurgy, mining, plastics, petroleum, chemical industry, medicine and other industries. UV has special technical advantages such as fast, accurate and low analysis cost.
In the field of environmental protection and food, UV can quickly screen out whether the harmful substances in the sample exceed the standard through direct testing.
JV-2000 has excellent test performance in the metal electroplating solution industry and leather industry. It can test the hexavalent chromium content in electroplating and the hexavalent chromium content of colorants in plastic and leather industries. The stability and accuracy of the test are excellent in the industry.
JV-2000 is widely used for testing electroplated coatings, including 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, etc.
