Discussion on Maintenance of ZBD Whiteness meter

The ZBD Whiteness Meter adopts a double photocell electric compensation type electric measuring circuit, and uses the photoelectric effect to measure the ratio of the radiance of the diffuse reflection on the surface of the sample to the radiance of the complete diffuse reflector under the same irradiation conditions to achieve the measurement of whiteness. the goal of.

Since the ZBD Whiteness Meter was put into production, it has played its due role in the verification of the whiteness of paper, pulp, fiber fabrics, powder, ceramics, enamel, paint and other objects. But in the early 1990s, the third generation of Whiteness Meter has been successfully developed and put into use, while the old specification ZBD Whiteness Meter still occupies a considerable proportion in various paper mills. For example, in Sichuan, it accounts for about 6 intestines. Therefore, how to play the due role of the old instrument and strengthen the maintenance and maintenance of the instrument is still of great significance. This paper discusses several problems in instrument maintenance.
