Function :

Brightness Tester*-Whiteness meter*-ISO brightness*-Digital whitening testing machine is used to test the whiteness. It also can test the paper’s transparency, opacity, light scattering coefficient and light absorption coefficient, also can define printing ink absorption values of paper and cardboard. The meter can menstruate many times and gives series of arithmetic measuring result. The testing data will store while powering off for a long time.
 

Standard andCharacter:

The meter is designed according to GB******3(standard lighting substance and lighting observing condition, modeling D*5 lighting. It adopts d/o lighting observing geometry terms (ISO***9), ISO***0 (ISO brightness), ISO***1 (Opacity),etc. The diffuse diameter is **0mm. It uses light absorber to eliminate the influence caused by the specimen’s mirror reflecting light.
 

Field:

It is widely applied in papermaking, fabric, printing, plastic, ceramic and porcelain enamel, construction material, chemical industry, salt making and other testing department that need to test whiteness.
 

Technical data:
1. Zero excursions: ≤0.1

2. Result excursion: ≤0.1

3. Result error: ≤0.5

4. Repeating error: ≤0.1

5. Mirror reflecting error: ≤0.1

6. Dimension of specimen: the diameter of specimen over *0mm or *9mm, thickness below *0mm

7. Power: ~**0V±*0%, *0Hz, 0.3A

8. Ambient condition: temperature 0°C~*0°C, humidity below *5%

9. Dimension and net weight: **5(L)mm×**0(W)mm×**5(H)mm, *0kg
