Powder Whiteness Tester portable Lab Handheld Digital Whiteness Meter

Product Description
WSB series digital display whiteness meter is mainly suitable for white and near white objects or powder surface whiteness measurement. The whiteness value consistent with the visual acuity can be accurately obtained.The instrument uses the principle of photoelectric conversion and A / D conversion circuit to measure the radiance energy reflected on the sample surface. After signal amplification, a / D conversion and data processing, the corresponding whiteness value is displayed at last.
Functional characteristics
1. AC and DC power supply, low power consumption configuration, small and beautiful appearance design, convenient for field or laboratory use (portable whiteness meter).
2. It is equipped with low voltage indication, automatic shutdown and low power consumption circuit, which can effectively extend the use time of battery (portable whiteness meter).
3. It adopts large screen and high-definition LCD display, which has comfortable reading and is not affected by natural light.
4. With low drift and high precision integrated circuit and high efficiency and long life light source, the instrument can work
stably for a long time.
5. Reasonable and simple optical design can effectively ensure the accuracy and repeatability of the measured value.
6. Simple operation, can accurately measure the opacity of paper.
7. Adopt the national standard white board to transfer the standard value, and the measurement is accurate and reliable.
