Tritorimetrul și spectrofotometrul sunt ambele folosite pentru a măsura diferența de culoare, dar principiul lor de lucru și metoda de măsurare sunt diferite.

By measuring the reflection or transmission of the light of three basic colors, red, green and blue, the color difference meter calculates the three stimulus values (L, a and b values) of the sample, so as to obtain the color difference value between the sample and the standard color. Tristimulus value chromatic aberrator can measure the color brightness, chroma and hue of the sample, is a commonly used portable chromatic aberration instrument, suitable for some simple chromatic aberration measurement.

The spectrophotometer uses spectrophotometry to decompose the light into different wavelengths of the spectrum, and then measure the intensity of each wavelength of the light, calculați reflectanța sau transmisia spectrală a probei, and then get the chromaticity coordinates and color difference of the sample. The spectrophotometer can measure the spectral information of the sample, and the measurement of color details is more accurate and fine. It is suitable for precision color measurement and color matching.

Care este diferența dintre un cromometru tricromatic și un spectrofotometru?

Prin urmare, the tritorimeter is suitable for some simple color measurement, while the spectrophotometer is suitable for more complex and precise color measurement. There is also a difference in price between tristiometry and spectrophotometer. Tristiometry usually has a lower price, while spectrophotometer has a higher price. În ceea ce privește aplicarea, tri stimulus value color difference meter is usually used for some simple color comparison and measurement, cum ar fi compararea dacă culoarea diferitelor loturi este consecventă, judecând dacă produsul îndeplinește cerințele de culoare. The spectrophotometer is suitable for fine color measurement and matching fields, precum imprimarea, strat, textile și alte industrii cu cerințe ridicate de acuratețe a culorii.

In a word, the trichromatic value chromatic difference meter and the spectrophotometer are different in color measurement, and the choice of the appropriate instrument needs to be determined according to the specific measurement requirements and application scenarios
