1. A diagnostic system, comprising:
a first sensor embedded within a structural metal for exposure to hydrogen for generating a signal response to both the hydrogen and one or more parameter;
a second sensor embedded within the structural metal for generating another signal response to the one or more parameter, with a hydrogen-suppressing layer to suppress any response of the second sensor to the hydrogen; and
a controller in communication with the first and second sensors for:
distinguishing the signal response of the first sensor from the signal response of the second sensor to characterize the hydrogen,
collecting a concentration of the characterized hydrogen a downhole equipment is exposed to over time;
correlating the concentration of the characterized hydrogen the downhole equipment is exposed to over time with an observed degradation of the downhole equipment; and
providing predictive capabilities of the downhole equipment being exposed to the characterized hydrogen over time.
