Whiteness meter TP-A11

Name: Whiteness meter TP-A11
Brand: Labtron.best
SKU: TP-A11
Rating: 5 (894 reviews)

Whiteness meter TP-A11 is used to measure the whiteness of objects. Its compact, advanced circuit design ensures the accuracy and stability of measurement data. It measures ISO (R457) whiteness and fluorescence whitening of the materials. The whiteness meter is provided with light absorber to eliminate the influence of specular reflection of the sample.
