The whiteness meter is a special instrument used to measure the whiteness of the blue light on the surface of the object. The sixth-generation intelligent whiteness detector of Topp conforms to GB3978-83: standard illuminator and lighting observation conditions, and its technical performance conforms to the JJG512-2002 whiteness meter The measurement results are suitable for the whiteness of products tested by various manufacturers and quality inspection agencies. The instrument uses pulse flash technology (lights on during the test, lights off after the test), energy-saving and environmental protection; simple linear calculation method, one-key zero calibration, high accuracy; fast digital wave algorithm, two seconds to complete the measurement; measurement results digital display, also The data can be printed out with a printer; its fully sealed design can meet the measurement requirements of various production sites.
Before the whiteness measuring instrument came out, people used visual inspection to evaluate the whiteness of the product. However, the visual method is affected by human physiology, mind, light source, observation environment and other factors, so it is difficult to obtain a unified evaluation result. In order to solve the problem of consistency in the quantitative evaluation of whiteness, people have standardized a variety of more general and accurate whiteness formulas, and many companies and metrological verification departments are also equipped with various whiteness meters, which can reduce people’s evaluation of products. Controversy over the degree of whiteness.
The whiteness meter is an important tool for evaluating the whiteness of products
In daily life, white objects can be seen everywhere, such as: white paper, white clothes, white ceramics, white walls, white salt and so on. There is a saying that white is all-match, whether it is clothes or walls, whether it is ceramics or paper, people prefer white. At the same time, white is also a symbol of the quality of industrial and agricultural products. In the production areas of salt, rice, flour, building materials, textiles, papermaking, ceramics, coatings, etc., the degree of whiteness is an important index for evaluating product quality. However, it is not enough for the production industry to judge the whiteness with the naked eye, and the whiteness meter is needed for accurate measurement.
