It removes all subjectivity involved in colour grading, supplying unbiased readings that are unaffected by operator or environment. Comprehensive Selection of Standard Colour Values The PFXi-195 Series of colorimeters automatically measure colour and display the results directly, either according to the traditional grading scales that have been widely adopted as industry standards for colour assessment and control, or in terms of internationally recognised CIE values and spectral data.
