1. A coreflood system, comprising:
a housing including an inlet end and an outlet end;
an inlet positioned at the inlet end;
an outlet positioned at the outlet end;
two chambers positioned within the housing between the inlet and the outlet, configured to retain porous media,
where the two chambers are in series along a fluid flow pathway through the coreflood system;
a partition extending from an inner surface of the housing and positioned between the inlet and the outlet;
a pH sensor provided in a sensor mounting location in the housing,
where the pH sensor has access to the fluid flow pathway.
