Name

Brightness Tester(Printer)

Model

XT-48BN

Function

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:

§ Measure ISO(R457) and fluorescent material’s fluorescent whiteness

§ Measure Light stimulus value Y10

§ Measure opacity op

§ Measure transparency T

§ Measure light scattering coefficient S and optical absorption coefficient A

§ Measure ink absorption value

Key Features

§ Has excellent appearance and compact structure ,and advanced circuit design can

ensure accurate and stable measurement data

§ Simulate D65 illuminator to illuminate

§ 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

§ 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

§ Added the printer and used the imported Thermal Printer , no need to use ink and

colored tape, no noise and fast speed

§ Equipped with RS232 interface can communicate with the computer software

§ Has power-off protection, Correct data would not lose
