Overview
QIWEI WSB-2 whiteness meter is an LCD digital display instrument that displays the result value on the LCD screen by measuring objects. Measurement range is 0~ 199.9, measurement aperture is φ 30, mainly used for measurement of whiteness value of objects or powders, and can also measure Opacity of thin sheet materials. It is often used in Quality control department or scientific research department for testing.
Features
1. LCD digital display design, intuitive display of measurement results
2. Measurement range, covering 0~ 199.9
3. The measurement aperture is φ 30mm, suitable for a variety of samples
4. LED Illuminant, Good Stability
5. Repeatability and small drift
6. Opacity and measurement whiteness
Principle
By measuring the intensity of the reflected light on the surface of the object and the characteristics of the Light spectrum, the diffuse reflected light is collected by the integrating sphere and converted into an electrical signal to calculate the whiteness value of the object. The whole is composed of Illuminant, Optical inspection system, detection system, data processing and display system, and adopts the blue light whiteness R457 standard.
Applications
Coating paints, plastics, flour, white cement, ceramics, paper, starch, salt
Steps
1. Connect the power supply to ensure that the working environment meets the requirements
2. Measuring location of the object to be measured
3. Start the instrument for measurement
4. Read the whiteness value displayed on the LCD screen
5. Recording or processing measurement data
Notice
• Operating temperature should be kept within the range of 5~ 35 ° C
• relative humidity not exceeding 85% RH
• Use AC 220V/50Hz power supply
• Avoid use in bright light or vibration environment
Periodically calibrated to ensure measurement accuracy
