What is the accuracy of the CHEMetrics test kits?
The accuracy of CHEMets test kits (with the exception of Formaldehyde, Glycol, Nitrate and Nitrite CHEMets) is + of each color standard increment. The accuracy of ULR CHEMets, VACUettes, and Formaldehyde, Glycol, Nitrate and Nitrite CHEMets test kits is + 1 color standard increment. The accuracy of the Titrets test kits varies with the analyte concentration because the Titret ampoules have a non-linear scale. At twice the minimum concentration for a particular kit range, the accuracy is + 10% error. The accuracy of Vacu-vials test kits using CHEMetrics-generated calibrations is typically + 10% error at 75% of full range (FR), + 20% error at 25% of full range, and + 30% error at CHEMetrics practical detection limit (PDL), the lower limit of the stated test range.
