Overview
QIWEI WSB-1Y whiteness meter is a Portable fluorescent whiteness meter with a measurement aperture of φ 15 and a resolution of 0.1. The instrument is used to measure the whiteness value of white or nearly white objects or powders, and can accurately measure paper Opacity. It is widely used in paper Cardboard, Spinning & weaving, paints Coating, plastic products, white cement, starch, flour, cosmetics and other industries to detect product whiteness value and strictly control product mass.
Features
1. Portable design, easy to carry and use
2. Fluorescence whiteness measurement function
3. High resolution 0.1, Measurement accuracy
4. AC/DC dual-use power supply, suitable for a variety of working environments
5. Aluminum Encasement Box, Sturdy and Durable
Principle
The whiteness meter adopts LED Illuminant, and the illumination condition is 45/0. The whiteness value and fluorescence whiteness are determined by the measurement of the reflection of the object to blue light (R457).
Applications
Spinning & weaving printing and dyeing, paints Coatings, chemical building materials, paper Cardboard, plastic products, white cement, ceramics, enamel, porcelain clay, powder tale, starch, flour, salt, detergent, cosmetics
Standards
R457 Blu-ray whiteness standard
Steps
1. Turn on the instrument power
2. Align the measurement aperture to the sample to be tested
3. Read the whiteness value on the LCD LCD display
4. Record measurement results
Notice
• Operating temperature range is 5~ 35 ℃
• relative humidity should be ≤ 85% RH
• Avoid use in a strong light environment
Periodically calibrate instruments to ensure measurement accuracy
• Clean the measurement aperture in time after use
