It is mainly applicable to the whiteness measurement of non colored objects or powders with flat surfaces, and can accurately obtain whiteness values consistent with visual sensitivity. The opacity of the paper can be accurately measured.
It can be widely used in the whiteness measurement of textile printing and dyeing, paint and coating, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, talcum powder, starch, flour, salt, detergent, cosmetics and other substances.
1. High definition LCD display is adopted, with comfortable reading and free from the influence of natural light.
2. Reasonable and simple optical path design can effectively ensure the correctness and repeatability of measured values.
3. Low drift high-precision integrated circuit and high efficiency long-life light source are adopted, which can effectively ensure the instrument to work stably for a long time.
4. Simple operation, which can accurately measure the opacity of the paper.
5. The national calibration whiteboard is used to transfer the standard value, and the measurement is accurate and reliable.
