1. A conductivity measurement device in a medicament generation system including a fluid circuit, the conductivity measurement device comprising:
a first conductivity measurement flow channel positioned in the fluid circuit;
a second conductivity measurement flow channel positioned in the fluid circuit;
an intermediate flow channel positioned in the fluid circuit and fluidly linking the first and second conductivity measurement flow channels to each other, the intermediate flow channel being at least partially bounded by a portion of a molded rigid case and a film adhered to the molded rigid case and being configured to maintain a constant content concentration of a fluid in a fluid flow from the first conductivity measurement flow channel to the second conductivity measurement flow channel; and
a controller having a current source connected to the first and second conductivity measurement flow channels, the controller being configured to apply alternating voltages at frequencies that are different, each frequency being respective to one of the first and second conductivity measurement flow channels.
