This test strip is ideal to test high levels of peroxide in solutions. The easy dip-and-read procedure provides reliable results within 45 seconds
Hydrogen peroxide (H2O2) is a powerful oxidizer, which is found in many disinfectants as the main active ingredient. In order to facilitate handling and save shipment costs, disinfectants come often as a concentrate. At the point of interest, they are then mixed with water to obtain the necessary disinfectant potency.
