Portable Digital Whiteness Meter White Colour Meter   

 Description:    The whiteness meter WHME-206  is an instrument to measure the whiteness of substances. Consistent with the visual sensitivity Baidu value can be measured, after the reaction of fluorescent whitening whiteness and opacity measuring paper. Whiteness meter is widely used in papermaking, printing, textile printing and dyeing, ceramics, enamel, building materials, chemicals, grain, salt and other industries is mainly used to determine the object whiteness, yellowness, color and color, determination of paper (not) transparency, light scattering coefficient, the optical absorption coefficient and the ink absorption value.

Applications:
      Whiteness Meter WHME-206 is mainly used to directly measure the whiteness value of object or powder with flat surface. Can be widely used in whiteness measurement of textile printing and dyeing, paint, chemical building materials, paper board, plastic products, white cement, ceramics, enamel, talc powder, starch, flour, salt, detergent, cosmetics and other substances.

 

    * It consists of Light Source, Optical System, Detection System, Data Process and Display System. The whiteness Calculation Formula of the instrument is blue light whiteness R457.
    * Use of high quality imported components, good reliability.
    * The optical path design is reasonable, simple. Adopt filter system with correction, the whiteness can be reflected quantitatively.
    * No preheating after starting, measurements can be taken after simple calibration, easy to operate.
    * Pass strict inspection and testing, the instrument conforms to the JJG 512-2002 Whiteness Meter Verification Regulation. Also conforms to GB3978, GB3979, GB7973, GB7974, ISO2470, GB8904.2, QB1840, GB2913, GB13025.2,       GB1543, ISO2471, GB10339, GB5950, GB12911, GB2409 and other standards.
    * Able to memory 254 groups of measurement data.
    * Use USB data out put and RS- 232 data out put to connect with PC.
    * Provide Bluetooth data out put choice.
