Lovibond 146250 ChecKit Color Disc, Phosphate HR

Features:

• 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. Additional testing parameters can be added by purchasing additional discs and reagents - utilize the same comparator housing for all of your test.

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.
