Overview
The YUE FENG SBDY-2 Portable whiteness meter is a High Accuracy measuring instrument for the measurement of material whiteness. Measurement range is 0~ 100%. It has the characteristics of easy operation, clear reading and high Stability.
Features
1. LCD liquid crystal display, clear reading, not affected by natural light
2. Simple operation and high cost performance
3. Unique Positioning Structure and High Accuracy Light Path System Ensure Measurement Correctness and Repeatability
4. Low drift, High Accuracy, Stability Circuit System, with Long Life Illuminant, Ensure Long Stable Operation
5. Using the national calibration whiteboard to transfer the correction value, the measurement is more accurate
6. Equipped with low voltage indication function, prompting to replace the battery to ensure measurement accuracy
Principle
The instrument adopts R457 blue light whiteness formula. Under the condition of 45/0 illumination, the sample is irradiated by approximate A Illuminant, the reflected light signal is measured, and the whiteness value is output by High Accuracy circuit system.
Applications
Material whiteness measurement, quality control, laboratory analysis
Standards
National calibration whiteboard standard
Steps
1. Power Adapter or 6V battery
2. Adopt national calibration whiteboard for calibration
3. Align the instrument to the tested sample for measurement
4. Read the whiteness value through the LCD display
5. Pay attention to the low voltage prompt and replace the battery in time
Notice
• The instrument should be used in a relative humidity ≤ 85% RH environment
• Regular use of national calibration whiteboards for calibration
• Pay attention to the low voltage indication and replace the battery in time to ensure measurement accuracy
• Avoid Strong Vibration and Impact, Protect Optical System
• It is recommended to remove the battery when not in use for a long time
