Reflectance Meter Or Brightness Tester Photovolt Type Brightness is defined as the percentage reflectance of blue light only at a wavelength of 457 nm. Brightness is arbitrarily defined, but carefully standardized, blue reflectance that is used throughout the pulp and paper industry for the control of mill processes and in certain types of research development programs.Features - Diffuse reflectance is measured at an effective wavelength of 457 nm by using a suitable filter set or an equivalent device for modifying the spectral response and an instrument having diffuse illumination and perpendicular observation geometry
- Design to give a long and trouble free life
- Provides unmatched stability & Sets up in just few seconds
