Not all NSF Certified test kits are equal!
Certified products are given an accuracy rating to one of three levels: L1, L2, or L3. ITS has been awarded level L1 certification, the highest accuracy rating available. Only products bearing the NSF®-50 logo are NSF®-Certified*.
"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, 18.104.22.168 Water Quality Testing Devices and Kits, page 148 - 149
