Overview
LANDTEK WM-206 whiteness meter is an integrated Portable whiteness meter with the function of storing 254 sets of data. The instrument adopts high-quality imported components, reliable and stable measurement, and simple and reasonable optical path structure design. It meets JJG 512-2002 whiteness meter verification standards and Miscellaneous international standards. It adopts R457 blue light whiteness calculation formula with a resolution of 0.1. It is suitable for measurement of whiteness value of flat objects or powders on the surface, such as Spinning & weaving printing and dyeing, Coating paints, etc. The measurement hole is 18x11mm rectangular hole, and the measurement area is large.
Features
1. Using imported components, the measurement is stable and reliable.
2. The design of the optical path structure is reasonable and simple, and the modified color filter system can accurately Basis Weight the whiteness value of the object or powder after fluorescent whitening.
3. Define the whiteness value of the complete diffuse reflection to be 100, and the whiteness of the black surface to be 0.
4, simple operation, no need to preheat the boot, simple calibration can be measured.
5. Comply with JJG 512-2002, GB3978, GB3979, GB7973, GB7974, ISO2470, GB8904.2, QB1840, GB2913, GB13025.2, GB1543, ISO2471, GB10339, GB5950, GB12911, GB2409 and other standards.
6. The data output can be carried out through RS-232C, USB connection to the computer or Bluetooth selection.
Principle
WM-206 whiteness meter consists of Optical inspection system, Illuminant, Probe system, data processing and display system. Using R457 blue light whiteness calculation formula, Basis Weight whiteness value is obtained by measuring the reflected light on the surface of the object.
Applications
Spinning & weaving printing and dyeing, chemical building materials, paints Coatings, white cement, paper Cardboard, plastic products, ceramics, enamel, flour, powder tale, salt, starch, detergent, cosmetics
