NS820 Color Matching Spectrophotometer for car doors, windows,
front moldings colour control
A significant part of the post-accident repair process is ensuring
a seamless paint job without requiring the entire vehicle be
repainted. For body shops, this means that paint matching must be a
top priority. While you may have a good idea of the base color of
the vehicle, matching that color identically virtually impossible
without the use of modern technology. As such, spectrophotometers
are essential to pinpoint the perfect color match.
Description
NS820 Color Matching 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.
