Abstract:
The invention is about an optical sensor element (1) for use in an optical sample analysing apparatus (2), comprising a housing (3) which contains at least one optical sensor component (4). ,The optical sensor element further comprises a housing body (5) and a housing lid (6), which is removably connected to the housing body (5), so that in the assembled state the housing body (5) and the housing lid (6) are forming a fluid-tight housing (3), and wherein the housing lid (6) is equipped with replaceable moisture control elements (7). The invention further is about an optical sample analysing apparatus (2) configured to work as a modular nephelometric turbidity sensor device, with at least one optical sensor element (1') configured as light receiving element, and one optical sensor element (1) configured as light emitting element.
