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.
