Description

Colour is an important quality attribute of almost all products in production. The ColorLite sph9i is complemented by various probe heads variants and a wide range of accessories. Therefore the ColorLite sph9i system ensures colour measurement in different areas such as plastics, paper, textile and food industries. Permanent quality control minimizes waste in the production plant, effect increasing productivity by reducing time and costs.

Applications

• Reflection light colour measurement of granules, recycled pellets, regrind, extrudates and injection molding components
• Reflection and transmitted light measurement of films, PET packaging, textile fabrics and paper webs
• Measurement of liquids e.g. with a dipstick probe
• Other applications on request – we are happy to support you!

Measurement principle

Spectral colour measurement is the most accurate measurement method to achieve consistent and best-reproducible measurement results. The samples are illuminated with homogeneous, white light of high power LEDs. The surface of the product is scanned spectrally in 3.5 nm steps. The wavelength coordinates of 400 to 700 nm are shown in the desired colour scale. The ColorLite sph9i takes into account the appropriate type of light and the observer angle of the selected probe head variant.
