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, packaging, nonwoven, textile dyeing and printing, color printing, construction materials and ceramics, chemicals, paints, medicines, food, recycled pulp products and mineral industries. FEATURES • Large alpha-numeric display • Single-button simplicity of operation • RS-232 data output • Stores up to 99 readings; auto-calculates mean value • Built-in printer 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
