The Copper water quality test strips are safe and easy to use for fast accurate results with a range of 0 to 2 ppm (mg/L), which are typical copper levels found in tap, well, and stream water. Simply dip the test strip into a 200 ml sample of water for 15 seconds with a gentle back and forth motion, remove and shake off excess water, and match after 30 seconds but before 60 seconds to the colour chart to get the Copper level in the sample.
