About Whiteness Tester/Whiteness Meter/Brightness Tester

Name:Whiteness Tester/Whiteness Meter/Brightness Tester

Model: WSB-IV

Whiteness Tester/Whiteness Meter/Brightness Tester function:

Intelligent white tester use light measuring integral ball realization absolute spectrum diffuse reflection rate test. Its photoelectricity principle is sends out the light by the halogen tungsten lamp, enter filters the color piece and condensing lens compose the blue purple light. Enters the integral ball light after the integral ball endophragm diffuse reflection. Shines in on the test mouth test specimen, by the test specimen reflection light by the silicon photoelectric generator receive, transforms the electrical signal. And some group silicon photoelectric generator receive ball in vivo basis signal, two groups electrical signals separately enlarge, mix processing, obtains the determination result.
