Method and apparatus for instrumental analysis in remote locations

摘要: The present invention provides a method and apparatus for instrumental analysis in remote locations. In one embodiment, the of controlling cathodic protection being applied to metal structure having surface disposed an electrolytic environment comprising electrically connecting coupon structure, positioning at predetermined position relative within environment, applying agent effect measuring indication proximate coupon, comparing with value, adjusting response comparison. this respect, system efficacy electrical voltage current source measurement protection, connected passage receiving movement means structure. could also be used facilitate non-destructive testing locations, as well mitigate or prevent stray discharge.
