Digital Whiteness Meter

Name:Whiteness Meter Model:WSB-IV Introduction: 1.One have print function and the other one have no print function.Use pulsed-flash technology(The light illuminate when testing.The light go off after testing.) 2.The meter will not give out heat.Can starting up in 24 hours continuous. 3.Test white content of object surface.Use double touch switch.Stability and lamp life improve. 4.Digital display the results. Energy-concerving and environment-protective, auto calibration,easy to operate.Measuring accuracy is high. 5.Widely used in flour, starch, rice noodles, common salt , textile,plastic, porcelain clay ,paper, white cement, paint and so on department. Function: I1.ntelligent 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. 2.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. 3.And some group silicon photoelectric generator receive ball in vivo basis signal, two groups electrical signals separately enlarge, mix processing, obtains the determination result. Technical specification: 1. Diffuse illumination and vertical sounding method(d/o), simulation D65 illuminant use d/o illuminatingviewing and geometrical condition. Globe of diffusion diameter is 120.Measuring hole diapmeter is 20 mm.Have light adsorber ,can eliminate reflected ray of sample mirror face. 2. Repeatability: ≤0.1 3. Indicating value drift: ≤0.1 4. zero point: ≤0.1
