Purpose:
The SBDY-2 digital whiteness meter is mainly suitable for measuring the whiteness of white and near white objects or powder surfaces. It is possible to accurately obtain a whiteness value that is consistent with visual acuity. The opacity of paper can be accurately measured.
This instrument can be widely used for measuring the whiteness of objects such as textile printing and dyeing, paint and coatings, chemical building materials, paper plates, plastic products, white cement, ceramics, enamel, porcelain clay, talcum powder, starch, flour, salt, detergents, cosmetics, etc.

SBDY-2 portable whiteness meter features:
1. Adopting an LCD display screen makes reading more comfortable and not affected by natural light.
2. Simple operation, moderate measurement range, and high cost-effectiveness make it more suitable for user use.
3. The unique positioning structure and high-precision optical path system effectively ensure the correctness and repeatability of measurement values.
4. By adopting a low drift, high-precision, and stable circuit system, as well as an efficient and long-life light source, the instrument can effectively ensure long-term stable operation.
5. Simple operation can accurately measure the opacity of paper.
6. Using a national calibration whiteboard to transmit calibration values for more accurate measurements.
7. The instrument is equipped with a low voltage indicator function to prompt the user to replace the battery, ensuring accurate and effective measurement values.
8. Equipped with a measurement output interface, it can be paired with a recorder.
