摘要： A chemical indicator device for use in detecting exposure to an oxidizing agent, such as hydrogen peroxide, comprising a substrate or support upon which is disposed a chemical indicator composition (ink) for detecting an oxidizing agent, such as hydrogen peroxide. The chemical indicator composition further comprises an indicator dye that achieves a distinct range of different color changes with clear transitions between colors, upon exposure to different doses of the oxidizing agent, thus allowing for both a qualitative and semi-quantitative assessment of exposure to the agent.
