If your material is a coloured liquid* and you can shine a beam of light through it without particles, turbidity or bubbles stopping or scattering the beam, we can measure it with a PFX, PFXi, Model F or Comparator system.
If you can bounce a beam of light off a uniform, opaque liquid or solid we can measure it using an RT unit.
The Food Industry has a long history of measuring the colour of their products. The reasons for doing this are as varied as the industry itself but the main criterion is standardisation.
Controlling the colour of incoming materials enables the food producer to reject any that is substandard before offloading and during processing in order that the final colour satisfies the consumers' expectations.
