摘要 |
<p>[PROBLEMS] To be able to measure the flow rate of chemical substance (diffusion flux) diffused from a part being measured, e.g. floor surface, ceiling, wall face, furniture, easily and accurately without being affected by open air (indoor air). [MEANS FOR SOLVING PROBLEMS] In the bottom face (12a) of a hollow case (12) being pasted to an object (13) being inspected, an opening (14) for taking a chemical substance diffused from the object (13) into a case (12) is formed. On the inner surface of the case (12), a test piece (15) causing discoloring reaction to the chemical substance under wet environment is provide oppositely to the opening (14). The case (12) is provided with a transparent observing section (12a) for observing a variation in color of the test piece (15) while kept pasted to the object (13) being inspected.</p> |
