1. A reservoir module for use in a portable dialysis system comprising:
- a reservoir housing having four sides, a base surface, and a top surface, wherein said four sides, base surface, and top surface define an internal space;
a container adapted to contain dialysate;
a scale comprising a plurality of flex points physically attached to the housing and a surface located within the internal space for supporting the container; and
a conductivity sensor located within the internal space and configured to generate a value indicative of a sodium concentration in the dialysate while the dialysate is in the container, wherein the conductivity sensor comprises a coil in a circuit and an energy source in electrical communication with the circuit.
