Whiteness Meter
Introduction of Whiteness Meter
Whiteness Meter is widely used in various industries—such as papermaking, printing, textiles, ceramics, construction, chemicals, food processing, and salt production—for measuring an object’s whiteness, yellowness, color, and color difference. Additionally, it can evaluate paper opacity, transparency, light scattering and absorption coefficients, and ink absorption values.
Standard Accessories
- Main unit, non-fluorescent white standard plate, fluorescent whitening standard plate, D65 light source lamp, black trap, power cable, technical documentation, and optional printer.
This device is an essential tool for laboratories and quality control in industries that require precise whiteness, color, and transparency measurements.
Detail Features About Intelligent whiteness meter
- Color and Whiteness Measurement: Measures parameters like diffuse reflectance (Rx, Ry, Rz), lightness (L*), chromaticity (a*, b*), chroma (Cab), hue angle (hab), dominant wavelength (λd), and color difference metrics (ΔE*ab).
- Extended Functionality: Capable of measuring lead core density.
- Built-in Printer: The unit includes an imported thermal printer that operates quietly without ink or ribbon, ensuring high-speed printing.
- RS232 Interface: Connects with computer software for data communication.
- Additional Optical Measurements: Yellow index (YI), opacity (OP), scattering coefficient (S), absorption coefficient (A), transparency, and ink absorption.
- Memory Capability: Stores up to ten reference samples, and retains calibration and standard values even when powered off.
- Density Measurement: Measures reflective light density (Dy, Dz) for lead core concentration.
- Simulated D65 Illumination: Uses a D65 illuminant and CIE 1964 supplementary colorimetric system.
- d/o Geometry: Includes a 150 mm integrating sphere and 25 mm measurement aperture, with a light absorber to reduce specular reflection effects.
