Applications:
Mainly suitable for white and near-white objects or powder surface whiteness measurement. The whiteness value consistent with the visual sensitivity can be accurately obtained. This instrument can be widely used in textile printing and dyeing, paint and coatings, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, China clay, talc, starch, flour, salt, detergent, cosmetics and other objects of whiteness measurement.
Working principle:
The instrument uses the photoelectric conversion principle and the analog-digital conversion circuit to measure the brightness energy value reflected by the surface of the sample, through signal amplification, A/D conversion, data processing, and finally display the corresponding whiteness value.
Functional characteristics:
1. Ac, DC power supply, low power consumption configuration, small and beautiful shape design, easy to use in the field or laboratory (portable whiteness meter).
2. Equipped with low voltage indication, automatic shutdown and low power consumption circuit, which can effectively extend the battery’s service time (push-type whiteness meter).
3. Using large screen high-definition LCD LCD display, with comfortable reading, and not affected by natural light. 4, the use of low drift high-precision integrated circuit, efficient long-life light source, can effectively ensure the instrument long-term stable operation.
5. Reasonable and simple optical path design can effectively ensure the correctness and repeatability of the measured value.
6. Simple operation, can accurately measure the opacity of the paper.
7. The national calibration whiteboard is used to transmit the standard value, and the measurement is accurate and reliable.
