With spectrophotometer YR053419 // YR053421, it can easily realize the accurate transmission of color and can also be used as the detection equipment of accurate color matching system.

Technical Advantages
  • Silicon photodiode array (double 40 array) sensor
    The larger area of the double 40 array sensor, the strong light will not saturation, weak light sensitivity and a wider spectrum response range, to ensure the instrument measurement speed, accuracy, stability and consistency, master the core technology, and the international standard of the same platform, complete compatibility.
  • Adopt full waveband balanced LED light source
    The full waveband balanced LED light source ensures sufficient spectral distribution in the visible light range, avoids the spectral loss of white LED in specific waveband, and ensures the measurement speed and accuracy of the measurement results.
  • Grating spectroscopic technique
    Use Grating spectroscopic technique, with higher resolution, to make the color measurement more accurate.
  • Place the base safely to ensure that the whiteboard is not dirty.
  • Professional whiteboard, a lifetime never change color commitment
  • Fast charging
    Special fast charging mode, low voltage to remind charging or use off-duty time charging, to ensure the capacity and life of the battery (note: frequent repeated battery charging more harm).
  • New fashionable appearance design based on ergonomics
    The position of the hand holding and the measurement button are carefully designed to meet different holding habits, smooth and fine surface, resulting from the high-precision appearance processing art.
  • Equipped with three measuring apertures to meet the most samples measurement
    The Factory configuration of spectrophotometer YR053419 // YR053421 is with ø 8mm flat aperture, ø 8mm tip aperture, ø 4mm flat aperture, ø 4mm tip aperture, ø 1x3mm aperture, a total of five measuring apertures, to meet the most samples measurement.
  • Camera positioning can clearly observe the measured area
    Spectrophotometer YR053419 // YR053421 built-in camera positioning, through the camera real-time view, can accurately determine whether the object measured part is the target center, improve the measurement efficiency and accuracy.
  • Excellent errors between instruments and repeatability
    Ensure the consistency of measurement data of multiple equipment, to be used for color matching and accurate color transfer.
  • A variety of color spaces and observation light sources
    Offer CIE LAB,XYZ,Yxy,LCh,CIE LUV, S-RGB,HunterLab,βXY,DIN Lab99 Munsell(C/2) color spaces, and D65, A, C, D50, D55, D75, F1, F2 (CWF), F3, F4 and F5, F6 and F7 (DLF), F8, F9, F10 (TPL5), and F11 (TL84), F12 (TL83 / U30) a variety of light sources, to meet the special measurement requirements under different measurement conditions.
  • Adopt international common use d/8 SCI/SCE Synthesis technology
    Adopt D/8 (SCI/SCE) measurement structure to more objectively reflect the color itself, and reduce the impact of object surface texture on test results, in accordance with CIE No.15. GB/T 3978,GB 2893,GB/T 18833,ISO7724-1,ASTM E1164,DIN5033 Teil7.
  • Dual optical path system for more accurate color measurement
    Dual optical path system, optical resolution is less than 10nm in the visible range, can simultaneously measure the sample SCI, SCE spectrum.
  • PC software has powerful function expansion
    SQCX quality management software with YR053421 spectrophotometer is suitable for quality monitoring and color data management of various industries. Digitize user data color management.
