Product Details

Whiteness colorimeter YT

Device Name	Whiteness and chromaticity tester YT
Product Usage	This instrument is widely used in industries such as papermaking, printing, textile printing and dyeing, ceramic enamel, building materials, chemical industry, grain, salt production, etc. It is used to measure the whiteness, yellowness, color, and color difference of objects. It can also measure the opacity, transparency, light scattering coefficient, light absorption coefficient, and ink absorption value of paper.

Technical Characteristics	thisThe instrument complies withsimulationD65Illumination body illumination. adoptCIE1964Supplementing the chromaticity system andCIE1976（Lab*）Color space color difference formula;adoptd/oIllumination observation geometry conditions. Diffuse sphere diameter150mmMeasure the diameter of the hole25mmEquipped with a light absorber, it eliminates the influence of mirror reflection light on the sample.. §The instrument has added the function of measuring lead core concentration. §This instrument has added a printer and adopts an imported thermal printer core, which does not require the use of ink and ribbon, operates without noise, and has fast printing speed. §This instrument is equipped with standardsRS232Interface, can communicate with microcomputer software. §The reference sample can be a physical object or data. §The instrument can store and remember up to ten reference sample information. §The instrument has a memory function, so even if it is shut down for a long time and loses power, useful information such as memory zeroing, calibration, and the measurement values of standard and reference samples will not be lost.
