Equipment description:
ZL-9015B Portable Handheld whiteness meter is mainly applied to the non-color surface or close to the measurement of whiteness of the white flat object or powder, can be accurately obtained are consistent with the visual sensitivity whiteness. Objects by fluorescent brighteners can be used to antitank the fluorescence graced the white value. Paper opacity can be accurately measured. ZL-9015B Portable Digital display white tester-measurement accuracy, beautifully designed, and the password box package, easy to carry. Digital display white tester is ideal for the lab, go out to sample quality inspection field, the use of mobile work.
