UV proof tester

It includes the closest spectral characteristics of the sun's light source, high stability of the UV-visible spectrophotometer, fully functional control and data analysis software. It replaces the human body (In-VIVO) to measure the SPF value and various other important indexes of sun protection products and cosmetics, making measurement cost more economical, faster and more convenient.
