<p>A means for detecting total residual chlorine and color discriminating between color levels in a low chlorine environment and method for the same is disclosed. The detecting means includes a test reagent using Michler's thioketone, or indicator active analogues thereof, in combination with nonionic fluorosurfactant. A test strip containing the test reagent impregnated thereon allows visual discrimination among very low levels of residual chlorine and is useful for testing chlorine sanitized medical equipment such as hemodialysis units.</p> |
