Musktool-color touch screen color difference color imeter tester price
| Brightness Meter is widely applied in paper and cardboard, pulp, cotton and fabric, plastic, ceramic and porcelain enamel, amylum, construction material, chemical industry, salt making and other testing department that need to test whiteness, yellowness, color and chromatism, as well as transparency, opacity, light scattering coefficient and light absorption coefficient of paper. |
Function:
1. CIE (1982) whiteness (Ganz visual whiteness) W10 and color shift value Tw10. 2. ISO whiteness (R457 blue light whiteness) and Z whiteness (Rz). 3. Fluorescence brightness. 4. Whiteness of building materials and non-metallic mineral products WJ. 5. Hunt Whiteness WH. 6. Color of the object, diffuse reflection factor Rx, Ry, Rz, stimulus value X10, Y10, Z10, chromaticity coordinates x10, y10, brightness L *, chroma a *, b *, chroma C * ab, hue angle H * ab, dominant wavelength λd, excitation purity Pe, color difference ΔE * ab, brightness difference ΔL *, chroma difference ΔC * ab, hue difference ΔH * ab, Hunter system L, a, b. 7. Yellowness YI. 8. Opacity OP, light scattering coefficient S, light absorption coefficient A, transparency, ink absorption value. 9. Lead concentration. |
Standards:
ISO2470: paper and board Blu-ray diffuse reflectance factor method (ISO brightness); ISO2471: paper and cardboard is not transparent method; |
Feature:
1. New design of the motherboard, CPU using 32-bit ARM processor to improve the processing speed of the instrument, calculate the data more accurate and fast. 2. Using 5-inch TFT true color LCD touch screen, the operation more humane, new users in 1 minute to master the use of methods. 3. The use of advanced mechatronic design, to abandon the original hand-turning hand wheel, thus solving the original test cumbersome (must be rotated 4 times to finish the hand wheel to test a whiteness and color), but also to solve the hand wheel rotation Positioning error, truly a key to test the brightness and color. 4. Simulation of D65 lighting body lighting. The chromatic aberration formula of CIE1964 (L * a * b *) color space is supplemented by CIE1964. 5. Use d / o illumination to observe geometrical conditions. Diffuse ball diameter of 150mm, measuring hole diameter of 25mm, with a light absorber, eliminating the sample mirror reflection of light. 6. The instrument increases the function of measuring lead concentration. 7. The printer uses imported thermal printer core, without the use of ink and ribbon, work without noise, print speed. 8. Equipped with standard RS232 and USB interface, can be used to communicate with computer software.(optional with extra charge) 9. Reference can be physical, but also for the data. The instrument can store up to ten reference samples. 10. With memory function, even if the long-term shutdown power, memory, zero, calibration, standards and reference samples such as the amount of information will not be lost. |
