White cement usage Whiteness Meter Whiteness Difference Meter

(specially designed for white cement)

Model: TBT-60-W 

 

1. Introduction:

This Whiteness Meter is designed for whiteness measurement of white cement related to the new white cement standard, which measures the whiteness of various products and helps hues analysis, normally configured with manual powder press.

 

 

2. Measuring and display:

The instrument measure & display:
1. Hunter whiteness WH, blue light whiteness (R457), Gantz whiteness, building material whiteness, daily ceramic whiteness, etc.
2. CIE X, Y, Z tristimulus value, x, y chromaticity value.
3. Lab color space (measure brightness of product, analyze product hue and color cast).
4. L*a*b* chromaticity space (measure product brightness value, analyze product hue, color cast)
5. L*C*H* color space (measure product color and color saturation).
6. Yellowness Index YI.

 

 

3. Application range:

Especially designed for measuring white cement;

Meawhile it can test calcium carbonate, talc, kaolin, wollastonite, diatomaceous earth, bentonite, titanium dioxide, phosphor, flour, salt, washing powder, calcium powder and other powder samples.
