Fluid composition sensor device and method of using the same

A device for detecting fluid particle characteristics comprising:

• a fluid composition sensor configured to receive a volume of fluid, the fluid composition sensor comprising:
• a removable fluid flow component disposed within an internal sensor portion and configured to define at least a portion of a fluid flow path;
• a collection media assembly dock element configured to receive a replaceable collection media assembly comprising a collection media configured to receive one or more particles of a plurality of particles within the volume of fluid such that the replaceable collection media assembly is arranged within the internal sensor portion in a particle collection position;
• a housing defining the internal sensor portion and being selectively configurable between an open housing configuration and a closed housing configuration, wherein when the housing is in the closed housing configuration, a vertical compression force is applied to the replaceable collection media assembly so as to at least partially constrain the replaceable collection media assembly in a vertical direction;
• an imaging device configured to capture an image of at least a portion of the one or more particles of the plurality of particles received by the collection media;
• a controller configured to determine, based at least in part on the image, at least one particle characteristic of the plurality of particles of the volume of fluid;
• wherein at least a portion of the fluid flow path extends in a fluid flow direction that is at least substantially toward the collection media;
• wherein the collection media assembly dock element is configured to constrain relative movement between the replaceable collection media assembly and the imaging device in a lateral direction.
