The YN-BD02 digital Whiteness Meter is composed of a light source, an optical system, a detection system, a data processing and display system, and the overall whiteness value is blue light R457.
The whiteness of the satirical surface is 100 for the spectral diffuse reflectance ratio of 1, and the whiteness of the absolute black surface for the spectral diffuse reflectance ratio of zero is 0.
The digital Whiteness Meter is mainly suitable for whiteness measurement of white and near-white objects or powder surfaces. It is possible to accurately obtain a whiteness value that is consistent with visual sensitivity. The opacity of the paper can be measured accurately.
This instrument can be widely used in textile printing and dyeing, paint and coating, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, china clay, talcum powder, starch, flour, salt, detergent, cosmetics and other objects of whiteness measurement.
This instrument is designed in full accordance with the standard light source and illumination conditions stipulated by the International Illumination Commission (CIE), through strict testing and debugging, and implemented in the enterprise standard Q/TDKY02-2004, which can be applied to GB2913, GB5950, GB8940.1, GB12097, GB13025.2 and other national standards.
1. Imported original components, effective, low-loss switching power supply, good reliability. Effective light source system, up to 100,000 hours of measurement times, no need to change the light source.
2. Simple operation, reasonable and concise optical path design, using a modified color filter system, using 45/0 observation conditions, can eliminate the influence of the measured object due to surface gloss on the white measurement.
3. The reliable movable platform design can effectively avoid the light leakage of the measuring orifice. Large aperture measurement, more comprehensive and accurate indication value.
4. Simple operation, can accurately measure the opacity of the paper. The performance of the instrument is very stable, and the measurement data is reproducible.
5. The national calibration whiteboard is used to transmit the standard value, and the measurement is accurate and reliable.
6. The appearance design of the instrument is beautiful and generous, the color is eye-catching, safe and firm.
