An optical sensor is provided utilizing a disposable flow cell with a cell body, an inlet tube and an outlet tube providing a flow passageway extending between the inlet tube and the outlet tube through the cell body. The sensor comprises a first housing component comprising an open front end and a back end to which a removable light source is mounted and a second housing component comprising an open front end and a back end to which a light detector for detecting light emitted by the removable light source is mounted. The first and second housing components are detachably connected to one another, the open front ends of first and second housing components being tightly engaged to provide a sensor housing which accommodates and encloses the disposable flow cell. The light source and the detector are positioned at opposing sides of the cell body, an optical pathway extending along an axis between the light source and the detector through the cell body perpendicular to the flow passageway. The inlet tube and the outlet tube extend through apertures formed by corresponding recesses of the front ends of the first and the second housing component. |
