Ocean Optics - 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.
