Features :
1.Determine ISO Brightness (ISO Brightness, that is, R457 whiteness). For fluorescent whitened samples, it can also measure the fluorescent whitening produced by the emission of fluorescent substances.
2.Determine the lightness stimulus value Y10. Determine opacity (Opacity). Determine transparency. Determine the light scattering coefficient and absorption coefficient.
3.Simulate D65 illuminator lighting. Adopt CIE 1964 complementary chromaticity system and CIE 1976 (L*a*b*) color space color difference formula. Use d/o illumination to observe geometric conditions. The diameter of the diffusion ball is φ150mm, and the test hole diameter is φ30mm and φ19mm. It is equipped with a light absorber to eliminate the influence of the specular reflection light of the sample.
4.The appearance of the instrument is novel and compact, and the advanced circuit design effectively guarantees the accuracy and stability of the measurement data.
5.Using high-pixel LCD module, Chinese display and prompt operation steps, display measurement and statistical results, friendly man-machine interface makes the operation of the instrument simple and convenient.
6.This instrument is equipped with a standard RS232 interface, which can communicate with the computer software.
7.The instrument has power-off protection, and the calibration data will not be lost after power-off.
