What are the main features of the portable colorimeter? The main features of the color difference meter are: color difference meter: 1. Automatically compare the color difference between the sample and the tested product, output CIE_Lab three sets of data and â–³E, â–³L, â–³a, â–³ after colorimetry b Four sets of color difference data, providing a reference scheme for color matching. 2, with sample and single measurement mode to meet the needs of different places measurement, simple operation, accurate measurement. 3. The instrument is portable. There are two power supply modes, battery and external power supply, which are convenient and practical. 4, installed with the USB expansion interface, you can connect to the computer display. The color difference meter is widely used in the color management field of plastics, printing, paint ink, textile and garment industries. Benchtop colorimeter: a simple description of the color and chromatic aberration of the object (paper, etc.), the ISO brightness (blue lightness), the fluorescence whitening of the bending tester and the fluorescent whitening material, and the measurement of CIE whiteness (Ganz whiteness) And color cast values), measuring ceramic whiteness, measuring building materials and non-metallic minerals "target=_blank> mineral whiteness, measuring Hunter system Lab and Hunt (Lab) whiteness, measuring yellowness, measuring samples Opacity, transparency, light scattering coefficient and light absorption coefficient, and measurement of ink absorption value.
How to choose a portable colorimeter? Users may find this agitator-like situation: they are also colorimeter (color difference meter), the price difference is very large, and the measured results are also different. Therefore, in the purchase of color difference timing, some "performance indicators" must be noted:
1, is "portable colorimeter (color difference meter), or "spectrophotometer"
2, "Spectral luminosity color difference meter (portable color difference meter)" is divided into "0/45 degree" and "d/8 degree integrating sphere" two kinds of measurement-observation method
3, the difference of various "d / 8 degree integrating sphere" color difference meter (color difference meter):
3.1 Is it “Double Beam Measurement Principle†or “Single Beam Measurement Principleâ€:
3.2 Integrating sphere: The quality of the integrating sphere of the roughness meter is crucial to the performance of the color difference meter (color difference meter). At present, most of the inner sphere reflection layer on the market is a coating structure, and there are problems such as yellowing and peeling after using for a period of time. Once this happens, the color difference meter (color difference meter) cannot provide accurate measurement data.
4, user interface friendliness:
5, the overall product compatibility:
