Claim:
1. A method of measuring dialysate characteristics in a dialysis system comprising: receiving a substantially pure water flow upstream of a mixing chamber; diverting a portion of the substantially pure water flow through a diverting branch having an additive source to form an additive solution; mixing the additive solution with the undiverted substantially pure water flow the mixing chamber to form fresh dialysate; measuring an electrical characteristic of the additive in the fresh dialysate during a first time period using a sensor downstream of the mixing chamber and upstream of an exit port of the dialysis system configured to communicate with a dialyzer; ceasing introduction of the additive to the diverted portion during a second time period; and measuring the electrical characteristic of the pure water flow during the second time period using the sensor.
