CHECKIT®Comparator The AQUALYTIC® 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 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. Test Kits Together with the CHECKIT®Comparator, each test kit includes CHECKIT®Discs, cells, stirring rod and AQUALYTIC® tablet reagents (for 30 tests) for the desired test. The test kits are supplied in a sturdy and handy plastic case. The operating instructions provide a step-by-step explanation of how to conduct the water test, ensuring that even "nonchemists” can achieve reliable and accurate measurements in the minimum of time.
