A method of testing a system (10), which has at least one electro- chemical sensor (40) for detecting an analyte gas within a housing (20) of the system (10), and the housing (20) has an inlet (22), in- cludes exhaling in the vicinity of the inlet (22) of the housing (20) of the system (10) and measuring a response to exhaled breath to test one or more transport paths of the system. Measuring the response to exhaled breath may, for example, include measuring the response of a sensor (40) within the housing (20) of the system that is responsive to the presence of exhaled breath. The sensor responsive to the pres- ence of exhaled breath may, for example, include an electrochemi- cally active electrode responsive to a gas within exhaled breath. The electrochemically active electrode may, for example, be responsive to carbon dioxide or to oxygen. |
