Desktop Paper Whiteness Tester / Meter / Testing Machine / Equipment / Instrument / Apparatus / Device
Desktop whiteness tester, desktop whiteness meter, mainly used for whiteness measurement of objects or powders with non-colored surface smoothness, can accurately obtain whiteness value consistent with visual acuity.For an object treated with an optical brightener, it can quantitatively reflect the whiteness value after fluorescent brightening.The opacity of the paper can be accurately measured. Meeting the national first-class whiteness meter requirements, improved design, high precision and good stability.
