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.

A real-life example success story
Online colour measurement on steel coil at Salzgitter AG
With the online spectrophotometer sph9i the colour values are continuously measured and controlle during the running coil coating process. The system is equipped with an infrared sensor for measuring the material temperature and subsequent thermo-chromatic compensation. Furthermore, the system has a fully automatic calibration unit. The operator terminal is supplemented by an industrial PC and a touch screen monitor.

Further application examples:
Colour and optical density measurement in the plastic sheet production
The ColorLite system is characterised by the highest quality and easy using. Measured values are visualised on the integrated display and can be stored for later reference with optional SQL database software. The system can measure inline up 5 density units (D5). The completion of a colour change is no longer a guessing game. The device automatically controls the dosing unit where the colour starts to deviate from the standard, thus avoiding an the production of out of range goods. There is no waste and thus no expenses.
Granule measurement through glass
The measuring system consists of a touch screen PC built into a control cabinet, as well as the
proven sph9i spectrophotometer, the measuring head MA38-VA with a d/0° geometry or our MA80
which measures over a diameter of 80mm. The MA38-VA can be provided with an automatic
calibration unit.
Control units can by interfaced directly to automatically sort out off range during the production –
