Lovibond CheckitComparator is a compact, handy colorimetric unit which is suitable both for mobile and stationary analysis work. Supplied with a generous number of different colour scales, it provides the basis for a comprehensive, easy-to-use colorimetric analysis system. The CheckitComparator D55 enables the use of large path lengths. The mirror optics makes use of the view through the entire length of the cell.

CheckitDisc
Each CheckitDisc contains a continuous colour scale which makes it possible to achieve an exact colour match between the colour standard and the sample. These CheckitDiscs are specially manufactured in selected materials to maintain colour-stability over a long period and guarantee reliable, reproducible measurement results.

Instruction manuals explaining the various stages of analysis in simple, straightforward terms, are supplied with each CheckitDisc.
