Introduction
The instrument maily used to measure the whiteness,applied in paper, cardboard,textile, painting ,chemical building materials, plastic , cement ,food, salt, ceramics cosmetic etc Like the following:
1.Measure ISO(R457) and fluorescent material’s fluorescent whiteness
2.Measure Light stimulus value Y10
3. Measure opacity op
4. Measure transparency T
5. Measure light scattering coefficient S and optical absorption coefficient A
6. Measure ink absorption value
Standards
ISO 2469 ISO 2470 ISO 2471 ISO 9416 ISO 9416 GB/T 7974 GB/T 7974 GB/T 1543 GB/T 10339 GB/T 10339 GB/T 2913 GB/T 13025.2 GB/T 5950 GB/T 8424.2 GB/T 9338 GB/T 9338 GB/T 13173.14 GB/T 13835.7 GB/T 22427.6 GB/T 22427.6 FZ-T50013
Main Features
1.Has excellent appearance and compact structure ,and advanced circuit design can ensure accurate and stable measurement data.
2.Simulate D65 illuminator to illuminate.
3.Adopted d/o illuminating--geometrical viewing conditions.Diameter of the globe of diffusion is 150mm and diameter of the testing hole is 30mm.Light absorber is provide to eliminate the effect of mirror reflection.
4.Adopted large-screen high resolution LCD modules.English display and prompt steps can show the results of measurement and statistics. Good human-machine interface makes the instrument 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 the computer software
7.Has power-off protection, Correct data would not lose
