Overview
SBDY-3 digital whiteness meter is a whiteness measuring instrument of YUE FENG brand. It adopts LCD Display mode, Measurement range is 0~ 100%, Precision is 0.01. The instrument is simple in design and suitable for accurate measurement of whiteness value.
Features
1. Has RS-232 Communication interface, can be used to connect the printer.
2. Use effective, low loss switching power supply to make Reliability higher.
3. Adopt high-quality imported components to ensure more stable operation and longer service life.
4. Adopting a simple light path design makes it easier to use and maintain.
5. The use of reasonable sample holder and movable platform design can effectively avoid the phenomenon of light leakage from the measurement orifice.
6. Use the national calibration whiteboard to transfer the correction value to make the Measured value more accurate.
Principle
The instrument adopts D65 Illuminant and 45/0 illumination conditions, and performs measurement based on R457 blue light whiteness formula. Measurement accuracy and Stability are ensured through simple optical path design and specimen holder structure.
