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 color touch screen.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
