Product Overview

The SBDY-1PN Digital Whiteness Meter is a precision instrument used for measuring the whiteness of objects. It adopts the calibration value transmitted by the national standard whiteboard to ensure measurement accuracy. The product features a simple design and offers stable and reliable performance.

Product Features

1. Equipped with an RS232 communication interface, it can be used to connect a printer. 2. Utilizes a high-efficiency, low-loss switching power supply for enhanced reliability. 3. Incorporates high-quality imported components for stable operation and extended service life. 4. Features a streamlined optical path design for simpler use and maintenance. 5. Employs a well-designed sample holder and movable platform to effectively prevent light leakage from the measurement aperture. 6. Uses a nationally calibrated whiteboard to transfer correction values for more accurate measurements.

Working Principle

The digital whiteness meter operates based on the principle of light reflection. An internal light source illuminates the sample, and the reflected light signal is captured through a concise optical path design. This signal is then converted into an electrical signal by photoelectric components, processed, and displayed digitally as the whiteness value. Calibration is performed using a nationally calibrated whiteboard to ensure the accuracy and traceability of the measurement results.

Operating Steps

1. Power on and preheat. 2. Calibrate the instrument using a national standard calibration whiteboard. 3. Place the sample to be tested on the sample holder and movable platform, ensuring it covers the measurement aperture. 4. Press the measurement button to take a reading. 5. If printing data is required, connect a printer via the RS232 interface for output.

Precautions

• Ensure the instrument is preheated and stable before use. • Calibration must be performed using the matching national standard whiteboard. • When placing the sample, ensure it completely covers the measurement aperture to avoid light leakage that may affect results. • Perform daily maintenance as required by the manual to keep the optical path clean. • Avoid using the instrument in environments with strong electromagnetic interference or extreme temperature and humidity conditions.
