Therefore, whiteness is an important standard of sensory quality and naturally becomes these products. The important instrument in quality inspection, and the whiteness meter is a special instrument used to measure the whiteness of flour and so on. Its application can not only ensure the measurement results, but also the measurement time is relatively fast, which meets the needs of modern industrial production measurement.

In the process of using the whiteness tester, we will find that the whiteboard of the whiteness tester is an important part of it. In the test of the whiteness tester, the recalibration of the standard whiteboard and the regular calibration are the most common. For example, the instrument's random working standard whiteboard should be submitted at least once a year. This also shows that the standard whiteboard plays an important role in the determination of the whiteness of the sample. Therefore, in the course of using the whiteness meter, it is necessary to pay attention to the maintenance of the whiteboard.
Generally speaking, in order to prolong the service life of the whiteboard, the workers need to perform safe cleaning and storage. When storing, special attention should be paid to the storage environment of the whiteboard whiteboard, and it should be stored in a desiccator to avoid light. For the cleaning of whiteboard whiteboards, either clean water or absolute ethanol can be used. However, special attention should be paid to the fact that no matter which type of cleaning method is used, it must be placed in a dry box for inspiration after cleaning. use.
Whiteness Tester The maintenance and repair of the standard whiteboard is a skill that the inspector must master. It is of great significance to guarantee the authenticity of the test results. If the standard whiteboard of the whiteness tester is inadvertently contaminated, it should be promptly sent to the relevant testing department for re-calibration after the cleaning, so that the follow-up measurement work can be carried out smoothly.
