VTSYIQI Spectrophotometer Colorimeter Color Difference Meter Tester with TFT 3.5inch Capacitive Touch Screen Display Color Space CIE LAB,XYZ,Yxy,LCh,CIE LUV Measuring Aperture Φ8mm USB/RS-232 Interface Measurement Time 1.5s

About this item

(1)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 sensitivity analysis.

(2)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.

(3)it 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 NS800 and Japan spectrophotometer, when measuring any color objects, the biggest L*ab difference is within ±1.0. This is a breakthrough of NS800 high technology which realizes to be fully compatible with international market.

(4)The spectrophotometer is equipped with high-end color management software which can connect PC to achieve more extension functions.It can store 1000 standard values and 10000 sample color difference values. The gigantic database can be used at any time during measurement.

(5)Application Industry: it can be used in textile, printing and dyeing, clothing, footwear, leather, chemical, plastic, film, pigment, paint, ink and other color industries to control color quality, color analysis, sample testing, production line testing. For texture testing can be used Multiple average tests.
