Copper kits are usually of two types: compleximetric or titration based. Some kits measure only ionic copper and others measure both ionic and chelated copper. This kit uses a highly sensitive catalytic compleximetric based procedure to measure all types of copper to less than 0.01 mg/L in marine or freshwater. MultiTest™ Copper performs over 75 tests and contains a reference sample for validation.
Accuracy
Range: Measures between 0–0.80 mg/L copper
Precision: Detectable changes on the color chart in 0.025mg/L & 0.0025 mg/L increments.
