The meter is used to measure whiteness.
It is widely applied in paper making, fabric, printing, plastic glaze, ceramic and porcelain, building materials, chemical industry, salt making and other testing department which need to test whiteness.
It can also test paper transparency, opacity, light scattering coefficient and light absorption coefficient.
The meter is designed according to GB3978-83 (Standard substance of illumination and illuminating observing conditions, modeling D65 illumination.
It adopts D/O geometrical terms observation illumination (ISO2469).
The diameter is 150mm diffuse.
It uses light absorber to eliminate the influence caused by mirror reflecting light from sample.
The meter can menstruate many times and give a series of arithmetic measurement results, the test data is stored while power off for a long time.
