High Accuracy Portable Whiteness Meter WSB-06 Whiteness Measurement Instrument

1.Product features

The repeatability accuracy can reach :dE*ab≤0.02, and the inter-machine difference can reach :dE*ab≤0.2

Supports Android/ ios/HarmonyOS/wechat Mini Programs /Windows programs

400-700nm full-band balanced LED light source and UV light source

National first-class metrology qualified

Dual-column high-precision CMOS array sensor

10nm resolution grating spectrophotometry technology

It offers over 30 measurement parameters and 37 evaluation light sources

The camera's viewfinder positioning allows for a clear observation of the measured area. It automatically calibrates, with the reference being Zr02 with a reflectivity greater than 90%, eliminating the need for frequent whiteboard calibration

The WSB-06 whiteness meter from CHNSpec Technology is versatile and can accurately measure the whiteness of calcium carbonate, paper, talcum powder, white cloth, etc. It is suitable for multiple industries. Its repeatability dE*ab is ≤0.02, and the inter-instrument difference dE*ab is ≤0.25, with extremely high measurement accuracy. The 3.5-inch full-color screen is intuitive to operate, allowing for quick parameter setting and result viewing, thereby enhancing efficiency. The wavelength range of 400-700nm precisely covers key bands and accurately measures whiteness, making it a reliable choice for quality control and quality monitoring in various industries.
