Product Description WT-7700 Grating SpectrophotometerIntroduction:The instrument adopts 1000 line precision blazed grating as the spectroscopic element, the silicon photocell array with large photosensitive area as the detector, the full spectrum led with high life as the light source, and the optical resolution is less than 10nm in the visible light range.Under the condition of d/8 geometric optical illumination recommended by CIE, WT-7700 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 WT-7700, it can easily realize the accurate transmission of color and can also be used as the detection equipment of accurate color matching system.Spectrophotometer WT-7700 is also widely used in the color quality control of various products. WT-7700 is equipped with high-end color management software, which is connected to the computer to realize more function expansion. The instrument has stable performance, accurate color measurement and powerful function. It is widely used in plastic electronics, paint and coating, textile printing and dyeing, printing paper, automobile, medical treatment, cosmetics and food industries, as well as scientific research institutions and laboratories etc.Features:1. D / 8 geometric optical structure, conforming to CIE No.15, GB / T 3978, GB 2893, GB / T 18833, iso7724 / 1, ASTM e1164, din5033 teil7;2. Adopt combined LED light source with high life and low power consumption, including UV / excluding UV;3. Switchable 8mm & 4mm aperture( the flat/ tip measuring aperture can be switched easily, which is suitable for more tested sample)4. Dual optical path system, the optical resolution in the visible range is less than 10nm, which can measure the SCI and SCE spectrum of the sample at the same time;5. Accurate spectrum and lab data, used for color matching and accurate color transmission;6. High hardware configuration: 3.5-inch TFT true color screen, capacitive touch screen, 1000 line blazed grating, siliconphotocell array detector with large photosensitive area, etc;7. USB / Bluetooth dual communication mode, wider adaptability;8. Super dirt resistant and stable standard white calibration board;9. Large capacity storage space, which can store more than 30000 pieces of test data10. 2/10 standard observer's angle, multiple light source modes, multiple surface color systems, meet various standards of chromaticity indicators, and the needs of various customers for color measurement;11. Camera locating position and Stabilizer cross measurement position;12. PC software has powerful function expansion;SpecificationModelWT-7700Optical GeometryReflect: di:8°, de:8°(diffused illumination, 8-degree viewing angle)SCI (specular component included)/SCE (specular component excluded) ; Include UV / excluded UV light sourceConforms to CIE No.15,GB/T 3978,GB 2893,GB/T 18833,ISO7724-1,ASTM E1164,DIN5033 Teil7Characteristicdouble apertures for accurate color analysis and transmission in laboratoryIt is used for precise color measurement and quality control in plastic electronics, paint and ink, textile and garment printingand dyeing, printing, ceramics and other industries, and for fluorescent sample measurement.Integrating Sphere SizeΦ40mmLight SourceCombined full spectrum LED light source, UV light sourceSpectrophotometric ModeFlat GratingSensorSilicon photodiode array (double row 40 groups)Wavelength Range400~700nmWavelength Interval10nmSemiband Width10nmMeasured Reflectance Range0-200%Measuring ApertureMAV:Φ8mm/Φ10mm;SAV:Φ4mm/Φ5mmSpecular ComponentSCI&SCEColor SpaceCIE LAB,XYZ,Yxy,LCh,CIE LUV,s-RGB,HunterLab,βxy,DIN Lab99 Munsell(C/2)Color Difference FormulaΔE*ab,ΔE*uv,ΔE*94,ΔE*cmc(2:1),ΔE*cmc(1:1),ΔE*00, DINΔE99,ΔE(Hunter)Other Colorimetric IndexWI(ASTM E313,CIE/ISO,AATCC,Hunter),YI(ASTM D1925,ASTM 313),Metamerism Index MI,Staining Fastness, Color Fastness, Color Strength, Opacity,8° Glossiness,555 tone classificationObserver Angle2°/10°IlluminantD65,A,C,D50,D55,D75, F1,F2(CWF),F3,F4,F5, F6,F7(DLF),F8 ,F9,F10(TPL5),F11(TL84),F12(TL83/U30)Displayed DataSpectrogram/Values, Samples Chromaticity Values, Color Difference Values/Graph, PASS/FAIL Result, Color OffsetMeasuring TimeAbout 1.5s (Measure SCI & SCE about 3.2s)RepeatabilitySpectral reflectance: MAV/SCI, Standard deviation within 0.08% (400 nm to 700 nm: within 0.18%)Chromaticity value: MAV/SCI, within ΔE*ab 0.02 ( When a white calibration plate is measured 30 times at 5 second intervals afterwhite calibration)Inter-instrument ErrorMAV/SCI, Within ΔE*ab 0.15(Average for 12 BCRA Series II color tiles)Measurement ModeSingle Measurement, Average Measurement(2-99times)Locating MethodCamera Locating,stabilizer cross positionDimensionL*W*H=129X76X217mmWeightApprox 600gBattery3.7V,5000mAh Li-ion battery, 6000 measurements within 8 hoursIlluminant Life Span5 years, more than 3 million times measurementsDisplayed Data3.5-inch TFT color LCD, Capacitive Touch ScreenData PortUSB, Bluetooth 4.2Data StorageStandard 1000 Pcs, Sample 30000 PcsLanguageSimplified Chinese, English, traditional ChineseOperating Environment0~40oC, 0~85%RH (no condensing), Altitude < 2000mStorage Environment-20~50oC, 0~85%RH (no condensing)Standard AccessoryPower Adapter, User Guide, PC Software(Download from office website), USB cable, White and Black Calibration Cavity, ProtectiveCover, Wrist strap, 8mm flat aperture, 8mm tip aperture, 4mm flat aperture, 4mm tip apertureOptional AccessoryMicro Printer, Powder Test BoxNotesThe specifications are subject to change without notice.
