"Visual colorimetric methods are accurate only to +/- half the difference between the adjacent color blocks, and thus the confidence limits for these methods are wider at higher concentrations (e.g., above 1.5 mg/L). Where portable colorimeter test kits are affordable, these are the most accurate kits available for use at POOLSIDE." - 2016 Annex to the Model Aquatic Health Code- Scientific Rationale, 4.7.3.5 Water Quality Testing Devices and Kits, page 148 - 149
