Brightness Colorimeter Zb-a

Cosmetic etc. Main Features1. Has excellent appearance and compact structure, andAdvanced circuit design can ensure accurate and stableMeasurement data. 2. Simulate D65 illuminator to illuminate. Adopted CIE 1964Supplementary standard colorimetric system and CIE 1976(L*a*b)color space and color difference formula. 3. Adopted d/o illuminating--geometrical viewing conditions. Diameter of the globe of diffusion is 150mm and diameter ofThe testing hole is 30mm. Light absorber is provide to eliminateThe effect of mirror reflection. 4. Adopted large-screen high resolution LCD modules. EnglishDisplay and prompt steps can show the results of measurementAnd statistics. Good human-machine interface makes theInstrument easy to operate. 5. Added the printer and used the imported Thermal Printer, No need to use ink and colored tape, no noise and fast speed. 6. Equipped with RS232 interface, can communicate with theComputer software7. Has power-off protection, Correct data would not lose8. Can store 9 reference samples ( sample or data)Technical parameters1. Power: 220V± 10%, 50HZ2. Indication accuracy: Chromaticity coordinate is 0.0001Others are 0.013. Data's stability: ≤ 0.1 within 30min4. Repeatability: Rx Ry and Rz s≤ 0.01, chromaticity coordinateS≤ 0.0010, . R457 s≤ 0.105. Sampler size: Diameter of the testing plane should be largerThan 30mm while the thickness less than 40mmDimension: 360*264*400mmNet Weight: 23kg1.
