Brigthness Tester - Jinan Drick Instruments Co., Ltd.

Introduction:

The meter is widely applied in papermaking, fabric, printing, plastic, ceramic and porcelain enamel, construction material, chemical industry, salt making and other testing department. It is used to test the whiteness, yellowness, color and chromatism of specimen, as well as transparency, opacity, light scattering coefficient and light absorption coefficient of paper.

Characters:

Reference can be practicality or data; The meter can maximum store ten references’ information; it can do test many times and give series of arithmetic measuring result; Digital display and the result can be printed out; The testing data will be stored while powering off for a long time.

Technical data:

1. It simulates D65 lighting engineering and adopts CIE1964 complementary color system and CIE1976 (L*a*b*) color space chromatism formula.

2. It adopts d/o lighting observing geometry terms (ISO2469, ISO2470, ISO2471). The diffuse diameter is 150mm and the test hole diameter is 25mm. It uses light absorber to eliminate the influence caused by the specimen’s mirror reflecting light.

3. Test repeat: σ (Y10) <0.1, σ (X10, Y10) <0.001.

4. Accuracy: ??10<1.0, ??10 (??10) <0.01.

5. Specimen dimension: test area≥?30mm, thickness≤40mm

6. Power: 170~250V, 50Hz, 0.3A

7. Test condition: temperature 10~30??/span>, relative humidity≤85%

8. Dimension and net weight: 345(L)mm×260(W)mm×425(H)mm, 16kg
