    Abstract: Assemblies and methods for monitoring the cathodic protection of underground or submerged structures may include a coupon assembly including a conductive test coupon and a reference electrode for determining the voltage potential difference of the protected structure without substantially interrupting surrounding current sources. The reference electrode may be at least partially covered with an electrolytic material in electrical contact with the surrounding environment via a plug including a porous material. A method of installation of the assembly may allow a single technician to install the coupon assembly using a probe rod without extensive on-site excavation. The coupon assembly may be configured to seat securely with the probe rod for stability during installation, and release from the probe rob when the probe rod is separated from the coupon assembly and withdrawn from the ground, leaving the coupon assembly at a preselected depth or preselected distance from the protected structure.

    Abstract: Methods and assemblies may be used for determining and using standardized spectral responses for calibration of spectroscopic analyzers. The methods and assemblies may be used to calibrate or recalibrate a spectroscopic analyzer when the spectroscopic analyzer changes from a first state to a second state, the second state being defined as a period of time after a change to the spectroscopic analyzer causing a need to calibrate or recalibrate the spectroscopic analyzer. The calibration or recalibration may result in the spectroscopic analyzer outputting a standardized spectrum, such that the spectroscopic analyzer outputs a corrected material spectrum for an analyzed material, and defining the standardized spectrum. The corrected material spectrum may include signals indicative of material properties of an analyzed material, the material properties of the material being substantially consistent with material properties of the material output by the spectroscopic analyzer in the first state.

    Abstract: An embodiment of an electrode watering assembly includes a cap having a cap body with a reservoir adjacent to a proximal electrode end of a permanent reference electrode when installed thereon. The cap body may include (i) a distal cap end defining a distal opening configured to be disposed around the proximal electrode end, (ii) a proximal cap end defining a proximal opening, and (iii) an outer wall defining an overflow port therethrough to receive overflow fluid from the reservoir and direct the overflow fluid out of the reservoir. The electrode watering assembly may include a conduit having a distal conduit end configured to be fluidly coupled to the proximal opening and a proximal conduit end configured to be positioned at a cathodic test station. Thus, fluid directed into the proximal conduit end is directed through the conduit and into the reservoir for watering at least the proximal electrode end.
