Application:
Whiteness colorimeter is widely used in building materials (cement, silicate, talcum powder, kaolin), daily chemicals (cosmetics, detergents, washing powder), ceramics (building ceramics, daily ceramics), flour, salt industry, food, Beverage, textile, flax, fiber, chemical industry, plastics, metallurgy, ultrafine powder, papermaking, printing, measurement, commodity inspection, etc.
Feature:
1.Wide range of applications:
The instrument can perform reflective measurement on solid samples, powder samples, pasty samples, silk samples and other surfaces.
2.Good measurement performance:
The computer-aided design is adopted to make the spectral characteristics of the instrument measurement sensor conform to the CIE standard observer response curve, and can accurately obtain the XYZ tri-stimulus value.
3.Rich color system and chromaticity value:
The instrument provides a variety of color systems, whiteness values and reference color differences, etc.
4.High automation and multi-function:
The instrument can automatically collect and process data during operation, and the operation is simple and fast. The instrument also has a complete editing function, the user can input or modify the data and color difference target value of the standard whiteboard through the keyboard, and can choose the output mode arbitrarily.
