1. A reference sensor component comprising:
a container cap removably coupled to a sample container configured to receive a sample;
a reference conduit extending from an underside of the container cap, the reference conduit comprising a reference conduit cavity;
an aeration port along a surface of the sample container, the aeration port configured to allow air to enter the sample container;
an air-permeable membrane covering the aeration port;
a wicking component disposed within part of the reference conduit cavity having a wick distal end and a wick proximal end, wherein at least part of the wicking component is configured to be in fluid contact with the sample when the container cap is coupled to the sample container such that at least some of the sample is drawn by the wicking component in a direction of the wick proximal end; and
a reference electrode material disposed at the wick proximal end, wherein the reference electrode material is configured to exhibit a substantially stable electrode potential compared to an active electrode in electrical communication with the reference electrode material.
