Grating Spectrophotometer YR05495



YR05495 spectrometer is equipped with φ 8mm, φ 4mm, 1x3mm three measuring apertures, more adaptability, accurate measurement of color, stable performance, in plastic electronics, paint coating, textile printing and dyeing, printing paper products, automotive, medical, cosmetics and food industries, in scientific research institutions, laboratory fields are widely used.

YR05495 series grating spectrophotometer is Kalstein company spent 3 years, carefully designed, fully with independent intellectual property rights grating spectrophotometer. The instrument uses 1000 lines of precision shining grating as the optical splitter, built-in silicon photodiode array (double row 40 groups) sensor, imported white board, repeatability delta E* AB easily controlled within 0.03, the use of long life full spectrum LED as the light source, optical resolution in the visible range is less than 10nm.

Under the condition of d/8 geometric optical illumination recommended by CIE, YR05495 grating spectrophotometer can accurately measure the SCI and SCE reflectance data of samples / fluorescent samples, and also can accurately measure and express various color difference formulas and color indexes in various color spaces. With spectrophotometer YR05495, 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) sensorThe 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 sourceThe 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 techniqueUse 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 chargingSpecial 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 ergonomicsThe 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 measurementThe Factory configuration of spectrophotometer YR05495 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 areaSpectrophotometer YR05495 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 repeatabilityEnsure 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 sourcesOffer 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 technologyAdopt 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 measurementDual 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 expansionSQCX quality management software with  YR05495 spectrophotometer is suitable for quality monitoring and color data management of various industries. Digitize user data color management.
