Purpose:
The SBDY-1 digital whiteness meter is mainly suitable for measuring the whiteness of objects or powders with flat non colored surfaces. It is possible to accurately obtain a whiteness value that is consistent with visual acuity. For objects treated with fluorescent whitening agents, the whiteness value after fluorescent whitening can be quantitatively reflected. 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.

Instrument Features
A、 Using CAD computer-aided design to make the instrument's appearance more reasonable and perfect.
B、 Adopting high-efficiency, low loss switching power supply to enhance reliability.
C、 Using high-quality imported components for more stable operation and longer service life.
D、 Adopting a simple optical path design, it is easier to use and maintain.
E、 The use of a modified color filter system can quantitatively reflect the whiteness value after fluorescent whitening.
F、 By adopting a reasonable design of the sample holder and movable platform, the phenomenon of light leakage at the measurement hole can be effectively avoided.
G、 By using simple operations, the opacity of paper can be accurately measured.
H、 Using a national calibration whiteboard to transmit calibration values for more accurate measurements.
