The system has a damp proof housing (212) with housing interior atmosphere (214). The damp proof housing prevents a penetration of air humidity and water vapour into the housing interior atmosphere. A test element carrier (216) is installable in the housing interior atmosphere. The test element carrier has a retaining structure (218) and a test element (112), held by the retaining structure, for analyzing the liquid sample. The liquid sample is applied on the test element within the housing interior atmosphere.
