A fluid quality monitoring apparatus (100) comprising a fluid flow channel (120) having a photo sensing material (104) disposed upon a first surface and a light source emitting light (132) through an opposing light transitive surface (106). The condition of the fluid affects the absorption and reflection of the light. The penetrating light is received by the photo sensing material (104), which provides an output that can be utilized to analyze the condition of the fluid. The light can be provided via a plurality of LEDS, the incorporation of a radially distributed series of fiber optic strands, or any other light source. The sensing material can include defraction gratings, improving the monitoring process. The sensing material can be incorporated in a variety of configurations. The apparatus is preferably designed to be integrated between a fluid filter and the respective filter mounting bracket.
