Product Description
Product Details
Introduction Brightness Meter is widely applied in papermaking, fabric, printing, plastic, ceramic and porcelain enamel, construction material, grain, salt making and other testing department that need to test whiteness yellowness, color and chromatism.
Characteristics Menstruate many times and give series of arithmetic measuring result; Digital display and the result can be printed out; 1. Test objects color ,diffuse reflectance factor RX,RY,RZ; stimulus value X10,Y10,Z10, chromaticity coordinate X10,Y10,Lightness L*,Chromaticity a*,b*,Chroma C*ab,hue angle h*ab, dominant wavelengthλd; ChromatismΔE*ab; lightness difference ΔL* ; Chroma difference ΔC*ab; Hue difference H*ab; Hunter system L,a,b; 2. Test yellowness YI 3. Test opacity OP 4. Test light scatting coefficient S 5. Test light absorption coefficient. A 6. Test transparencies 7. Test Ink absorption value 8. Reference can be practicality or data; The meter can maximum store ten references’ information; 9. Take the average value; digital display and the test results can be printed out. 10. The testing data will be stored while powering off for a long time.
