While modern cars are technological marvels in themselves,
automotive color measurement requires the use of some of the most
advanced technologies available to ensure accurate color matching. Benchtop Spectrophotometer NS820 offer the highest level of quality control for truly objective
color measurement. The sophisticated optical geometries of these
instruments allow you to capture both color and appearance data to
monitor overall color harmony even in the presence of vastly
different materials. The data obtained by spectrophotometric
analysis provides a universal language that makes it possible to
create color standards, monitor color behavior, and communicate
color information across sites, operators, and materials.
Spectrophotometric data, however, doesn’t just allow you to measure
the color of automotive components in isolation; they also give you
the information you need to improve the quality and efficiency of
your manufacturing process.
Brief Introduction
Benchtop Spectrophotometer NS820 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.
