JR 557&558 Spectrophotometer uses the principle of combination LED precision spectroscopy, separates the light according to a certain wavelength interval, and adopts groups of sensor array to perform sensitive analysis. JR557&558 Spectrophotometer with higher accuracy is very sensitive to any colors.It not only can measure L*ab value and delta E value accurately, but also can display spectral reflectance curve which can realize color matching function and calculate the real parameters of various color formulas.
In the R&D process, JIURAN scientists and engineers measured various color samples from dark to light, white to black, and other standard color boards provided by ISO (International Standardization Organization). The parameters of test results are integrating with international standards.
JIURAN also analyzed the parameters from Japan,American and Germany spectrophotometers. The differences of L*ab absolute value between them are within ±1.5. Compared the L*ab value between BGD 557&558 and Japanese spectrophotometer, when measuring any color objects, the biggest L*ab difference is within ±1.0. This is a breakthrough of BIUGED high technology which realizes to be fully compatible with international market.
JR 557&558 Spectrophotometer is widely used in plastic, electronic, paint, ink, textile, garment,printing and dyeing, food, medical, cosmetic, industries, scientific research institutes, schools and laboratories.
It can measure reflectance spectrum and other color index precisely. JR 557&558 Spectrophotometer not only can help to perform color matching and color management studies, but also can control product quality management accurately.
