Overview
The CHNSPEC WSB-0 whiteness meter is a Portable measuring instrument for fast and accurate measurement of the whiteness of samples. It uses a 4mm test diameter, supports the connection of mobile apps and WeChat Mini Program for operation and data management, and has a screenless design that makes it small and lightweight.
Features
1. 9 whiteness indicators such as R457/ISO2470 blue light whiteness can be measured.
2. Accurate measurement, through the national metrology authentication.
3. Automatic calibration, one-click measurement, 1.5 seconds fast results.
4. Equipped with high-grade ceramic whiteboard, with high luminance value, dirt resistance, wear resistance, discoloration resistance.
5. Support connecting mobile app and WeChat Mini Program for control and data processing.
6.4Mm test diameter to meet the measurement needs of more small size samples.
Principle
The whiteness meter uses a 45/0 (45-degree annular illumination, 0-degree reception) measurement structure and conforms to GB/T 3978. It uses a full-band equalized LED Illuminant to illuminate the sample and calculates the corresponding whiteness value by measuring the light intensity of a specific wavelength (such as 457nm blue light) reflected by the sample through the receiver.
Applications
Paper, tale powder, flour, starch, Spinning & weaving, paint, cosmetics
Steps
1. Connect the device through the mobile app, WeChat Mini Program or computer software.
2. Align the instrument measurement port with the sample to be tested.
3. One-click trigger measurement.
4. After about 1.5 seconds, view the measurement results on the connected device.
Notice
• Ensure that the instrument is fully charged, and a single full charge can make continuous measurements about 7000 times.
• Automatic calibration of the instrument before measurement, please ensure that the Calibration plate (advanced ceramic whiteboard) is clean.
• When measuring, please completely cover the 4mm measurement diameter on the surface of the sample to be tested.
• The instrument has no screen, and all operations and data display need to be completed through a connected smart device.
• Pay attention to the zero drift and indication drift indicators of the instrument to ensure the stability of the measurement environment.
• Support massive Data storage and management through APP.
