Product Overview

The SBDY-1N digital whiteness meter is a measuring instrument under the YUE FENG brand, used to determine the whiteness value of objects. This model adopts a streamlined optical path design and is equipped with a reasonable sample holder and movable platform, effectively preventing light leakage during the measurement process.

Product Features

1. Utilizes a high-efficiency, low-loss switching power supply for greater reliability. 2. Incorporates high-quality imported components for stable operation and longer service life. 3. Features a streamlined optical path design, making it easier to use and maintain. 4. Employs a well-designed sample holder and movable platform to effectively prevent light leakage from the measurement aperture. 5. Uses a nationally calibrated whiteboard to transfer correction values, ensuring more accurate measurements.

Working principle

This digital whiteness meter operates based on the principle of light reflection. The internal light source of the instrument illuminates the sample under test. Through a concise optical path design, the reflected light signal from the sample is received, converted into an electrical signal, and finally processed and displayed as a whiteness value. Calibration is performed using a national standard whiteboard to ensure the accurate transmission of measured values.

Operating steps

1. Power on and warm up. 2. Calibrate the instrument using the national standard white calibration board. 3. Place the sample to be tested on the sample holder and movable platform. 4. Ensure the sample completely covers the measurement aperture to avoid light leakage. 5. Perform the measurement and read the whiteness value displayed on the screen.

Precautions

• Ensure the instrument is fully preheated before measurement. • Calibration must be performed using the accompanying national standard whiteboard. • When placing the sample, ensure it completely covers the measurement aperture to prevent light leakage from affecting results. • Keep the instrument and standard whiteboard clean to avoid contamination. • Please operate and maintain the equipment according to the instruction manual.
