This instrument is used to measure the blue light whiteness of object bodies, and the measurement data is accurate and reliable; This instrument complies with《JJG512-2021The measurement requirements of "standard level" whiteness meters in the Regulation on Measurement and Verification of Whiteness Meters ensure that the data deviation is always controlled within the leading range of the industry in the detection of flour, starch, Rice noodles, salt, textiles, printing and dyeing, chemical fiber, plastic, porcelain clay, talc, calcium carbonate, mineral powder, paint, paint, ceramics, enamel, paper, pulp and other materials.

Intelligent whiteness meter/Working principle of intelligent whiteness tester:

The instrument uses an integrating sphere to measure absolute spectral diffuse reflectance, and its optical principle is based on the emission of a semiconductor light sourceblueThe colored light directly enters the integrating sphere,blueAfter diffuse reflection on the inner wall of the integrating sphere, the colored light is irradiated onto the sample at the testing port. The spectrum reflected from the surface of the sample is received and converted into an electrical signal by a silicon photovoltaic cell after passing through a condenser, light barrier, and color filter group; There is also a silicon photovoltaic cell that receives the substrate signal inside the sphere. The two electrical signals are amplified separately and processed by the microcontroller to achieve the system functions of automatic zero calibration, working whiteboard calibration, and sample testing. Users can easily use this instrument to test the whiteness of various samples.
