Whiteness and chromaticity tester LWACT-A10 is based on a D/0 geometry with a 150 mm diffuser and a 30 mm test aperture, ensuring uniform illumination. It offers excellent stability of less than equal to 0.1 within 30 minutes for high-precision applications. This system supports measurements in both CIE and Hunter color systems (L, A, b), offering versatility for various industry standards. It is a reliable tool for industries requiring meticulous color and whiteness control.
