Overview
SBDY-1P digital whiteness meter is a whiteness measuring instrument of YUE FENG brand, using digital or LCD Display mode, Measurement range is 0~ 100%, Precision is 0.1, suitable for accurate whiteness detection.
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 is based on the whiteness formula R457 blue light whiteness. Under the conditions of D65 Illuminant and 45/0 illumination, the whiteness of the sample is measured through the optical path system, and the national calibration whiteboard is used for correction to ensure the measurement accuracy.
Applications
Whiteness measurement, quality control, material testing
Standards
National calibration whiteboard standard
Steps
1. Connect the power supply and turn on the instrument.
2. Use the national calibration whiteboard for calibration.
3. Place the sample in the sample holder to ensure that the measurement holes are aligned.
4. Start the measurement and read the whiteness value of the digital or LCD display.
5. Optional connection to the printer to output data through the RS-232 interface.
Notice
Make sure the power supply is 220V +/- 10% to avoid voltage instability.
• Regularly use the national calibration whiteboard calibration instrument to ensure accurate measurement.
• Avoid light leakage from the measurement orifice and place the sample correctly.
• Follow simple design principles when maintaining optical path systems.
• Use imported components and pay attention to the working environment to prolong life.
