Sell brightness tester/ brightness meter

Description

brightness tester/brightness meter
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?~*0?, humidity below *5% 9. Dimension and net weight: **5(L)mm×**0(W)mm×**5(H)mm, *6kg
