Product Description

Brightness Tester & Whiteness Tester

This brightness meter is mainly used to measure the whiteness of paper, paperboard, paper pulps, pulps of chemical fiber, cotton, chemical fiber, textile, plastic, starch, salt, white cement, porcelain clay and talcum powder, etc.

AREAS OF APPLICATIONS :-

  1. PAPER : Brightness, Opacity, Gloss 75, Chromaticity, Transparency, Soap-stone
  2. Barytes Powders : Brightness, Whiteness.
  3. Salts, Atta, etc. : Brightness, Whiteness.
  4. Pharmaceuticals : Brightness, Whiteness.
  5. Cosmetics : Brightness, Whiteness, Chromaticity
  6. Paints : Chromaticity, Hiding Power, Colour matching, Gloss 60.
  7. Detergents : Brightness, Detergency Action of Detergents.
  8. Ceramics : Brightness, Chromaticity, Gloss.
  9. Sugar : Colour Index as per ICUMSA Brightness, Chromaticity,Luminous Reflectance, Matching of Sugar Samples.
  10. Textiles : Brightness, Lustre of Fabric, Chromaticity of dyes, pigments and also of finished surfaces.
  11. Pigments, Dyes : Chromaticity.
  12. Mech. Engg. : Sheen.
  13. Coffee : Colourr matching.
  14. Minerals : Brightness, Whiteness.
  15. Plastics : Chromaticity, Gloss 45.


SPECIAL FEATURES :


1. Calibration through Software thus linearity & consistency of the reading increases.
2. Heating in the main unit is minimised
3. Our equipments run from 180 V AC up to 240 V AC, to take care of low voltages due to load shading. We recommend the use of CVT ( 230V,500VArating). The magnetic field of the CVT isolates the equipment from mains supply properly.
4. The interference of the equipment with RF signals & static Electro Magnetic fields are eliminated.
5. Minimum Maintenance
