A change in concentration of the corrosion inhibitor in the solvent is detected, on the basis of a change in impedance of the electrode surface film formed on the surface of the detection electrode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Corrosion protection performance degradation detection sensor, hot-water supply heating system, and facility apparatus","description":"A corrosion protection performance degradation detection sensor includes a detection electrode that reacts with the corrosion inhibitor dissolved in the solvent and forms on a surface thereof an elect","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9677992","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
