UP-6037 Digital Whiteness meter Tester for paper
Function
1. Determination of ISO whiteness (i.e. R457 whiteness). For the fluorescent whitening sample, the fluorescence whitening degree generated by the emission of the fluorescent material can also be determined
2. Determine the brightness stimulus value
3. Measure the opacity
4. Determining transparency
5. Measure the light scattering coefficient and absorption coefficient
6, measure the ink absorption value
The characteristics of
1. The instrument has a novel appearance and compact structure, and the advanced circuit design effectively ensures the accuracy and stability of the measurement data
2. The instrument simulates D65 lighting
3, the instrument adopts D/O illumination to observe the geometric conditions;Diffuse ball diameter 150mm, test hole diameter 30mm(19mm), equipped with a light absorber, eliminate the sample mirror reflected light influence
4, the instrument adds a printer and the use of imported thermal printing movement, without the use of ink and ribbon, no noise, printing speed and other characteristics
5, Color large screen touch LCD display, Chinese display and prompt operation steps to display the measurement and statistical results, friendly man-machine interface makes the operation of the instrument simple and convenient
6. Data communication: the instrument is equipped with a standard serial USB interface, which can provide data communication for the upper computer integrated report system
7, the instrument has power protection, calibration data will not be lost after power
