Portable Digital Whiteness Meter

The portable digital whiteness meter illuminates the surface of the sample with a built-in light source. The sensor receives the reflected light and converts it into an electrical signal. The processor calculates the whiteness value, which is then digitally displayed. It is used for on-site rapid determination of the whiteness of materials such as paper and plastics, making it suitable for production quality inspection and warehouse sampling checks.
Selection
When selecting a portable digital whiteness meter, consider a measurement range that covers the whiteness values of common materials. The instrument should be lightweight and suitable for handheld operation, with battery life sufficient for on-site testing requirements. Calibration plates must be provided as accessories to ensure data accuracy, and the protection rating should be suitable for use in workshop environments.
