CHECKIT® Comparator Test Discs are supplied as part of a complete test kit, or can be purchased individually as a replacement to expand your testing capabilities.
Continuous Color Gradient Color discs have a continuous color gradient making it possible to achieve a direct color match - no need to extrapolate the result between two color standards.
Step-By-Step Instructions Included with each color disc, the multi-lingual instructions provide an illustrated step-by-step explanation of how to conduct the test - ensuring that even "non-chemists" can achieve reliable and accurate measurements quickly.
Wide Variety of Parameters Many parameters have multiple testing ranges and methods available. Additional testing parameters can be added by purchasing additional discs and reagents - utilize the same comparator housing for all of your test.
