Wsb-1 Portable Digital Whiteness Meter Leucometer White Meter Wb=r457

(1)AC and DC power supply, low-power configuration, compact and beautiful appearance design, easy field or lab use(portable whiteness meter). (2)With a low voltage indication, auto power off and low-power circuit, which can effectively extend battery usage time( they push whiteness meter). (3)the use of large-screen high-definition LCD display, with comfortable reading and free from the influence of natural light. (4) The use of low-drift precision integrated and efficient long-life light source, which can effectively ensure that the instrument long time stability. (5)A reasonable, simple optical design, can effectively ensure the accuracy and reproducibility of the measured values. (6)The operation is simple, can accurately measure the opacity of the paper. (7)The use of national calibration standard whiteboard to deliver value, accurate and reliable measurements.

• WSB series digital whiteness meter integrally formed by the light source. optical systems, detection systems, data processing and display systems, the overall degree of whiteness is blue R457.
• WSB series digital whiteness meter mainly for white and brightness measurements near the surface of an object or a white powder. It can be obtained accurately consistent with the sensation level of whiteness. For the opacity of the aper can be accurately measured.
• The instrument can be widely applied to measure the whiteness of textile, paint， chemicals, building materials, paper, cardboard, plastic products, white cement, ceramic, enamel, porcelain clay, talc, starch, flour, salt, detergents, cosmetics and other objects.
• Measuring range: 0-199; Whiteness formula : Blue whiteness WB= R457
• Resolution : 0.1；Zero drift :≤0.2/10min
