CHECKIT^®Comparator

With continuous colour scale low cost - precise - reliable

Applications: Water Treatment (e.g. Drinking Water), Pools, Laboratory and
Field Testing, Special Applications

The Lovibond^® CHECKIT^®Comparator 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 two cells are filled with the water sample and one is placed directly into the left-hand compartment of the comparator, where it acts as compensation (blank) for coloured or cloudy samples.

The diffuser plate on the rear of the comparator is used to provide compensation for ambient influences and unfavourable lighting conditions.

The CHECKIT®Comparator D55 enables the use of large path lengths. The mirror optics makes use of the view through the entire length of the cell.

CHECKIT^®Disc

Each CHECKIT^®Disc contains a continuous colour scale which makes it possible to achieve an exact colour match between the colour standard and the sample. These CHECKIT^®Discs are specially manufactured in selected materials to remain 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 CHECKIT^®Disc.
