    Abstract: A concentration measuring apparatus is provided having a fluid sensing means, an optic transmission means, a signal processing means, and an interface means. The fluid sensing means comprises a reflective sensing media in a self-contained cassette. The cassette is operationally associated with a sample chamber. The cassette advances the reflective sensing media by a motor which is driven by the signal processing means. The optic means comprises a fiber optic line which is partially associated with a lamp and partially associated with a photocell. Light having a wave length in a specified range originates from the lamp, passes through a portion of the fiber optic cable and is cast upon the reflective sensing media. The altnerate portion of the fiber optic cable receives the reflected light from the reflective sensing media for transfer to the photocell. A signal is generated by the photocell representative of the change of reflectivity of the light from the reflective sensing media. The signal from the photocell is accepted by the signal processing means. The signal processing means contains an amplifier, an analog to digital converter, a computer and associated controls. The interface means is associated with the signal processing means. The interface means comprises a display, a 4-to-20 milliamp card and remote, explosion-proof switches for operator interaction with the concentration measuring apparatus. Also, the interface means is the link to an outside printer, an outside analog recorder as well as an outside host computer.
