Analyzer of colour

On-line Colour analyzer for Liquids

 

Advantages

Continuous on-line colour measurement for better process (product quality) control

Eliminates time-loss and cost for sampling andlaboratory measurements

Large illumination area, less sensitivity to window fouling, better repeatability (with bubbles in the stream in particular)

LED light source, minimal energy consumption,long lifetime

Low operating and maintenance costs

Colour can be measured in any colour scale (CIE XYZ, CIE Lab, ASTM 1500, ASTM D156 Saybolt, APHA, Hazen, etc.)

Double beam (sample and reference) design

 ColourSpec” is a process/industrial analyzer for in-line colour analysis of liquid product streams such as petroleum products (paraffin wax, oil, diesel, naphtha, etc.), edible oils, beers and malts, beverages and chemicals. 

It enables continuous (real time) monitoring and control of colour throughout the manufacturing process. Integrated new generation micro spectrometer, innovative LED light source and double beam (sample beam and reference beam) design allow accurate stable and reproducible colour measurements. This (i.e. measuring the whole transmission spectrum in the visible wavelength range not just using one or two wavelengths) also allows for the use of internationally recognised colour coordinate systems, such as CIE XYZ and CIE LAB with the subsequent translation of colour data to industry specific colour scales, as referenced by standardising bodies such as AOCS, DGF, ISO and ASTM.

The software (user interface, visualisation, data analysis, data logging and so on) can be customised according to customer’s needs and requirements.
