SenSafe® John's Copper Check 0-2ppm (NCW-480042)
Our patented aperture strips are unique in the way the water flows through them and detects the Free Copper more accurately and at a sensitivity that enables low detections of free copper in water (as low as 0.05 ppm and up to 2.0 ppm).
This test can be used to detect copper in water in various environments and permits the measurement of typical copper levels in well water, tap water, pools and streams. The precise colour chart is found on the back of the bottle and no other reagents or accessories are needed for this simple test. We use trace amounts of chemicals on our strips which makes them extremely safe and non-hazardous. They are considered as Articles under OSHA and do not require SDS sheets. No interference from iron and works in a wide pH range.
