Whiteness meter LWM-A12 features a low zero drift of ≤ 0.1 %, which ensures precise and reliable measurements even during extended operation and repeated testing. The compact, advanced circuit design ensures the accuracy and stability of measurement data. It measures ISO (R457) whiteness and fluorescence whitening of the materials. Our whiteness meter is provided with light absorber to eliminate the influence of specular reflection of the sample.
