Description of  NS820 Portable Spectrophotometer with 4mm aperture

NS820 spectrophotometer has the same specification with NS810 spectrophotometer, but it adopts 4mm aperture, fit for some special sample use.

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 NS810 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.

APPLICATIONS

NS820 spectrophotometer is widely used in plastic, electronic, painting, coating, ink, textile, garment, printing and dyeing, food, medical, cosmetic, industries, scientific research institutes, schools and laboratories.  It can measure reflectance spectrum and other color index precisely. NS810 spectrophotometer not only can help to perform color matching and color management studies, but also can control product quality management accurately. The instrument is equipped with high-end color management software which can connect PC to achieve more extension functions.
