What is a whiteness meter? What is the principle of whiteness meter? What measure does the white meter measure? For this series of questions, we have to answer one by one.

Baidu Instrument, as the name implies, is an instrument for measuring the whiteness of a substance. It is possible to measure Baidu values ​​that are consistent with visual acuity, reflect the whiteness value after fluorescent whitening, and measure the opacity of paper.

Whiteness meter is widely used in papermaking, printing, textile printing and dyeing, ceramic enamel, building materials, chemical industry, food, salt and other industries. It is mainly used to determine the whiteness, yellowness, color and color difference of objects, and to measure the (non)transparency of paper. Light scattering coefficient, light absorption coefficient, and ink absorption value.

Whiteness meter is a professional instrument for measuring the whiteness of blue light on the surface of an object to control the whiteness of the product surface. The digital display of the measurement result can also be processed and printed by the single-chip microcomputer. Easy to operate, high measurement accuracy. Applicable to food, chemical, ceramics, printing and dyeing and other departments that need to measure and control the whiteness of products.

Intelligent whiteness meter principle: The intelligent whiteness meter uses the photometric integrating sphere to measure the absolute spectral diffuse reflectance. The optoelectronic principle is that the tungsten halogen lamp emits light. After the condenser and color filters form blue-violet light, the light entering the integrating sphere is diffusely reflected on the inner wall of the integrating sphere, and is irradiated on the test mouth sample. The light reflected by the sample is formed by Silicon photocells receive and convert into electrical signals. In addition, a silicon photocell receives the substrate signal inside the sphere, and the two electrical signals are respectively amplified and mixed to obtain the measurement result.

Whiteness meter can measure ISO brightness (R457 whiteness). For fluorescent whitening samples, it can also measure the degree of fluorescent whitening produced by the emission of fluorescent substances. Meanwhile, the brightness meter can also measure the brightness stimulus value. Y10, opacity, transparency, light scattering coefficient and absorption coefficient and other parameters. These are all based on the principle of whiteness meter - photometric integrating sphere to measure the absolute spectral diffuse reflectance.

Bright Annealed Stainless Steel Tube, which is bright annealed after the Stainless Steel Tube is formed to the target dimension and tolerances.

Bright annealing is the annealing of stainless steel sheet and strip continuously in a controlled-atmosphere furnace (depicted). ... The advantages of bright annealed strip are improved surface finish, reduced buffing costs, and improved corrosion resistance.

Stainless Steel is usually sold in the [annealed" condition. It means that the material is in the [soft" or annealed condition. ... This cold work can be eliminated by heat treatment (annealing) that will restore the original soft condition. Annealing increases ductility and eliminates internal stresses.
