The Lovibond® TA 4 online system enables instant monitoring of colour
quality throughout the manufacturing process. With assisted
implementation by trained Lovibond® personnel, it is designed to be an
easy-to-use monitoring system with the accuracy guaranteed of the
Lovibond® brand.
The online system provides objective colour data for continuous process
control, allowing near real-time process information to be obtained at a
low analytical cost. The system can be used for the measurement of
constituent concentrations, early detection of trace contaminants and
quality assurance analysis. Analytical results can be fed back for
automatic process control and optimisation.
This new generation of online colorimeters utilise diode array
spectrophotometers which measure a near real-time response across the
spectrum (380 to 780 nm) or less. This spectrophotometric approach
allows for the use of of internationally recognised colour coordinate
systems, such as CIELAB and CIE xzY with the subsequent translation of
colour data to industry specific colour scales, as referenced be
standardising bodies such as AOCS, DGF, ISO and ASTM.
