Brontes Colorimeter
|
The Brontes Colorimeter
is a high-speed, high-precision instrument made especially for
measuring colors and luminance in a production environment.
Colors are measured according to the
human eye (CIE1931) and numerous color spaces are supported.
Because of its small and compact size,
the Brontes can be easily integrated into your production
environment and is ideal for use in a laboratory as
well.
