Project Description

The spectrophotometer with d/8 Sphere is a high-reliability and high precision instrument that can deal with a wide range of applications.  

S2 spectrophotometer is widely used in plastic, electronic, paint, ink, textile, garment, printing and dyeing, food, medical, cosmetic, industries, scientific research institutes, schools and laboratories.

Exceeding most industry color standards, the S2 precisely measures reflectance  spectrum and other indices. Not only does the S1 spectrophotometer perform color matching and color management, it accurately controls product quality. For more advanced functions, this color measuring instrument comes with sate-of-the-art color management software ready to connect to a PC.


Research & Development

Vteke meticulously measured color samples, ranging from dark to light, white to black and other International Standardization Organization (ISO) color boards as part of the R&D stage. All parameters of the S2 test results were then integrated with international standards.

Vteke also analyzed the spectrophotometer parameters from Germany, Japan and the United States. Results showed that L*ab absolute value differences between them are within ±1.5. The comparative L*ab values between S2 and the Japanese spectrophotometer, when measuring any colored objects, has a difference within ±1.0. With such carefully tested parameters, the S2 is a compatible instrument across the global market.

Easy to use and understand the menu.

Aesthetic design perfectly combined with ergonomics structure.

45/0 geometrical optics structure like human eye sees.
