ZB-B Digital whiteness tester - ZB-B

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
