Whiteness, transparency and milling degree are displayed in digital form by measuring the amount of reflected and transmitted light from the sample grain it is more accurate than the conventional type of whiteness meter.
Place a small quantity of sample on the plate and operate the lever by left hand. Holding a pencil or pincette by right hand and measure the grain length or thickness by moving each grain to the groove.
Grain rigidity has a close relationship with quality. Grain with high moisture content or chalky grain shows less rigidity. As a consequence, milling recovery would be less.
For accurate sifting of a sample for making purity tests.
Note If other meshes are required please specify in your inquiry.
