product key technologies
The WSB series digital whiteness meter is mainly suitable for measuring the whiteness of white and near-white objects or powder surfaces. The whiteness value consistent with the visual perception can be accurately obtained. This instrument can be widely applied to the whiteness measurement of objects such as textile printing and dyeing, paint and coatings, chemical building materials, paper and paperboard, plastic products, white cement, ceramics, enamel, kaolin, talcum powder, starch, flour, table salt, detergents, cosmetics, etc.
The instrument utilizes the principle of photoelectric conversion and adopts an analog-to-digital conversion circuit to measure the radiance energy value reflected from the sample surface. After signal amplification, A/D conversion, and data processing, it finally displays the corresponding whiteness value.
Feature
1. AC and DC power supply, low power consumption configuration, compact and beautiful appearance design, convenient for field or laboratory use (portable whiteness meter).
2. It is equipped with a low-voltage indication, automatic shutdown and low-power consumption circuit, which can effectively extend the battery life (push-type whiteness meter).
3. It adopts a large-screen high-definition LCD liquid crystal display, which is comfortable to read and not affected by natural light.
4. It adopts low-drift high-precision integrated circuits and high-efficiency long-life light sources, which can effectively ensure the long-term stable operation of the instrument.
5. A reasonable and simple optical path design can effectively ensure the accuracy and repeatability of the measurement values.
6. With simple operation, it can accurately measure the opacity of paper.
7. National standard whiteboards are adopted to transfer standard values, ensuring accurate and reliable measurement.
