Brightness and Color Meter
68-50
The model 68-50 Brightness & Color Meter makes
measurement of brightness, color and opacity affordable
in Production and QC applications. The Brightness &
Color Meter measures color, color purity, degree of
yellowness, degree of whiteness, color matching and color
fastness. The TMI Brightness and Color Meter operates
in accordance with CIE Publication No. 15.2 “Standard
of Colourimetry” and was designed to meet ISO, ASTM,
TAPPI and other International Standards.
APPLICATIONS
Applications of the instrument include paper, pulp,

The Brightness and Color Meter can be used to measure:
• Color parameters, color differences between two samples for objective comparisons.
• The degree of whiteness of a sample sheet to evaluate light scattering coefficient, absorption coefficient,
degree of opacity yellowness.
• The instrument can assess the degree of color changing and staining in textile color fastness.
• The unit adjusts UV-content in radiation channel, thus enabling the users to adjust the UV-content in the light
source of the instrument to measure ISO brightness values, whiteness values and colorimetric values.
• The 68-50 includes infrared spectrum R950. functions to measure residual ink concentration of recycled
paper according to TAPPI T 567. ERIC- Effective Residual Ink Concentration can be reported as unit less
or as parts per million (ppm)
• This instrument can also be used for quality control on products, color control and measurement for document
and antique restoration as well as export and import commodity examination
