Products Description

The CRX-51 is a domestic commercial non-contact or in-line color measurement instrument that can be used for both laboratory measurements and in-line measurements of reflectance spectra and chromaticity data.

Laboratory measurement (equipped with control stand) - suitable for non-contact color measurement of cosmetics, paint/ink wet films and antiques without contamination and damage to the sample.

In-line measurement - In-line color measurement system can continuously obtain product color data, get more comprehensive and richer information about the sample, make faster decisions, optimize the production and processing process and ensure product quality. Real-time adjustment of production parameters can save costs and improve production efficiency.

  • Built in calibration without human intervention

  • The full band balanced LED is used as the lighting source, and the service life is worry free
