Testing for Copper in water can be very time-consuming, not to mention costly and dangerous. Often, the operator is required to have a high level of skill in order to be able to manipulate the liquid-based testing kits normally used. With our Copper Check test strips you can say goodbye to difficult tests. Simply dip one test strip into your water sample and swirl, remove the strip and match with the closest color match to determine your level of Copper. Accurate results for home, lab, and on-site have never been this easy.
