Color measurement spectrophotometer for color value with small aperture NS820
NS820 spectrophotometer is developed by 3nh with independent intellectual property rights. It features with stable performance, precise measurement and powerful functions in the leading position of the same industry.
In the R&D process, 3nh scientists and engineers measured various color samples from dark to light, white to black, and other standard color boards provided by ISO (International Standardization Organization). The parameters of test results are integrating with international standards.
3nh also analyzed the parameters from Japan, American and Germany spectrophotometers. The differences of L*ab absolute value between them are within ±1.5. Compared the L*ab value between NS820 and Japan spectrophotometer, when measuring any color objects, the biggest L*ab difference is within ±1.0. This is a breakthrough of 3nh high technology which realizes to be fully compatible with international market.
